5 Lab 5 – Interrupts (part 1)
5.1 Aim
This laboratory practical will introduce you to the concept of interrupts, which are an important
feature of all modern computer systems, including microcontrollers. This lab will enable you to
comprehend the purpose of interrupts, and the way in which they can be utilised to optimise wasteful
processes such as event polling loops. Consideration of the different hardware interrupts available on
the PIC16F877A will be undertaken in this laboratory practical, and procedures will be developed for
their proper configuration and servicing.

interrupts available on the PIC16F877A.
Knowledge of how interrupts are implemented and serviced on the PIC16F877A.
Ability to develop code that utilises i ...
1.CPU INSTRUCTION AND EXECUTION CYCLEThe primary function of the .pdfaniyathikitchen
1.CPU INSTRUCTION AND EXECUTION CYCLE:
The primary function of the cpu of a computer is to execute the sequence of instructions stored
ina memory which is an external to the cpu.The cpu must first fetch an instruction from the
memory before it can be executed .The sequence of operations involved in processing an
instruction constitutes an instruction cycle.This can be sub divided into two major phases i.e.,
fetch phase and execution phase.These two phases are performed in two cosecutive time slots
under the control of a clock.Hence these two operations are called as cycles .The time needed to
complete the execution of an instruction is known as INSTRUCTION CYCLE time .
a.FETCH CYCLE:The instruction is obtained from main memory during the fetch cycle.The
fetch operation can be described as \"send the address of the next instruction to memory and
recieve the instruction from the memory\".
b.EXECUTION CYCLE:The execution cycle includes decoding the instruction fetching of the
required operand and performing the operations specified by aninstructions opcode.In other
words it can be stated as \"Decode the fetched instruction if the operand is specified in the
memory then fetch that operand and execute the instruction \".
**INSTRUCTION CYCLE:
Thus the fetch and execute operations are carried out in synchronism with a clock is known as
instruction cycle i.e.,IC=FC+EC.
3.a.INSTUCTION FORMAT:Instruction format has one or more number of fields.The first field
is called as operation code field or opcode fielde which indicates type of operations to be
performed by the cpu.It also contains other fields known as operand fields.The cpu executes the
instructions using the information which resides in these fields.
b.WORD SIZE:A memory unit stores binary information in group of bits called words.The
number of bits in each word is often refered to as the WORD SIZE of a computer.Each word is
stored in one memory register.The word size in micro and mini computers ranges from 8 to 32
bits, and large computers usually have 32 or more bits in a word.
c.CLOCK RATE:A clock is a square wave , which is used to synchronize various devices in the
microprocessor and the system.Every microprocessor system requires a clock for its
functioning.The time taken for the microprocessor and the system to execute an instruction is
called clockrate.
4.FUNCTION OF GENERAL PURPOSE AND SPECIAL PURPOSE REGISTERS:
General purpose registers are available to store any transient data required by the program.For
example, when a program is interrupted its state, ie: the value of the registers such as the
program counter, instruction register or memory address register - may be saved into the general
purpose registers, ready for recall when the program is ready to start again.In general the more
registers a CPU has available, the faster it can work.
A Special Function Register (or Special Purpose Register, or simply Special Register) is a
register within a microprocessor, which controls or mon.

Deceptive Marketing (also known as “dark Marketing”) are tricks used in websites and apps that
make you do things that you didn’t mean to, like buying or signing up for something. The purpose of
this site is to spread awareness and to shame companies that use these patterns.
How does Deceptive Marketing work?
When you use websites and apps, you don’t read every word on every page—you skim read and
make assumptions. If a company wants to trick you into doing something, they can take advantage
of this by making a page look like it is saying one thing when it is in fact saying another. You can
defend yourself by learning about deceptive marketing.
Types of Deceptive Marketing
Trick questions
While filling in a form you respond to a question that tricks you into giving an answer you didn’t
intend. When glanced upon quickly the question appears to ask one thing, but when read carefully it
asks another thing entirely.
This is very common when registering with a service. Typically a series of checkboxes is shown, and
the meaning checkboxes is alternated so that ticking the first one means “opt out” and the second
means “opt in”. Confusing language is often also used. Currys PC World provides a good example of
this on their checkout collection
BRAIN Computer Interface (BCI) is a technique that
provides direct interface between the human brain and the
computer. BCI techniques are broadly classified into
invasive and non-invasive techniques. Non-invasive
techniques are becoming more popular and more research is
being done on this topic. There are various non-invasive BCI
techniques such as EEG, Electro-Oculography. EEG technique
deploys an electrode cap that is placed on the user’s scalp for
the acquisition of the EEG signal, which relates the scalp
potential differences to various complex actions. Classification
of the EEG signal has been made into several bands like alpha,
beta, delta, theta and mu suppression, each corresponding to
various states of being like relaxing, ranging over 8-14 Hz;
concentrating, ranging over 13-30 Hz; deep sleep, from 0-4
Hz; meditating from 4-8 Hz; moving your hands or legs or just
by imagining these motor actions respectively. As it is being
non-invasive in nature, it has an advantage over traditional
BMI, not being hazardous to health. With the advent of
technology the EEG acquisition devices are made more
compact, handy and wireless. Using the above mentioned
technique, a simple thought controlled wheelchair system has
been proposed in this paper. A section that briefly explains the
various blocks included in the system is also added in this
paper
Mechanism of fullerene synthesis in the ARC REACTOR (Vivek Chan 2013)Vivek chan
A mathematical model for the arc reactor which takes into account a. cooling and mixing of carbon vapour with a buffer
gas, b . non-isothermal kinetics of carbon clusters growth and c. formation of soot particles and heterogeneous reactions at
their surface has been developed. The model gives quantitative coincidence of experimental data with calculated values both
for the fullerene yield and ratio C70rC60 in the products of the arc synthesis run under widely varied conditions. Numerical
analysis of the model has shown that experimental data obtained for the arc synthesis strictly constrain the choice of the
mechanism of fullerene formation.
[Vivek Chan 2013]
EEG Acquisition Device to Control Wheelchair Using ThoughtsVivek chan
With the advancements in technology and health-care facilities, the number of senior citizens has increased and thus the number of elderly who find it difficult to walk. Hence there is a need for designing a wheelchair that is user friendly and involves fewer complexities. In this context, we propose a thought controlled wheelchair, which uses the captured signals from the brain and process it to control the wheelchair. This wheelchair can also be used by the physically challenged who depend on others for locomotion. Rehabilitation centers at hospitals can also make use of this wheelchair. In this paper, we explain the design and analysis of the thought-controlled wheelchair. In addition, we present some of the experiments that were carried out and the corresponding results in this paper.

Full Shri Ramcharitmanas in Hindi Complete With Meaning (Ramayana)Vivek chan
Ramcharitmanas (Devanāgarī: श्रीरामचरितमानस, IAST: ŚrīRāmacaritamānasa), also spelt as Ramacharitamanasa, is an epic poem in Awadhi dialect of Hindi, composed by the 16th-century Indian bhakti poet Goswami Tulsidas (c.1532–1623). Ramcharitmanas literally means "Lake of the deeds of Rama". Ramcharitmanas is considered as one of the greatest works of Hindi literature. The work has been acclaimed as "the living sum of Indian culture", "the tallest tree in the magic garden of medieval Indian poetry", "the greatest book of all devotional literature" and "the best and most trustworthy guide to the popular living faith of the Indian people".
The core of the work is considered by some to be a poetic retelling of the events of the Sanskrit epic Ramayana, centered on the narrative of Rama, the scion of the family tree of Raghu of the Sun Dynasty and the crown prince of Ayodhya who is also considered in Hindu tradition as one of the Avataras of Vishnu. However, Tulsidas never alludes to Ramcharitmanas as being a retelling of Valmiki Ramayana. He calls the epic Ramcharitmanas as the story of Rama was stored in the mind (Mānasa) of Shiva before he narrated the same to His consort Parvati. Tulsidas claims to have received the story through his guru, Narharidas. Tulsidas was unconscious (Acheta, Devanāgarī: अचेत) and the story was stored in his mind (Mānasa) for long before he wrote it down as Ramcharitmanas. The epic poem is, therefore, also referred to as Tulsikrit Ramayana (literally, The Ramayana composed by Tulsidas).

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Waiting time
Response time
CPU utilization
CPU efficiency
Measuring Processor Performance
► It means that the branch executed is not the
same as predicted by the processor.
In such a case, there is an additional
overhead in loading the data values for the
branch not executed by the processor.
► It refers to the process of loading data from
the memory and stores refer to writing data
back to the memory per unit time.► It refers to the number of processes that
complete their execution per unit time.
► It refers to the amount of time to execute a
particular process. It is also called
execution time.► It refers to the execution time for an
instruction.
► It refers to thee execution time for a
program.
It is the sum total of the execution time for
each instruction.
► It refers to the amount of time a process
has been waiting in the ready queue.
► It refers to the amount of time taken to
generate a response to a request.
► It refers to the fraction of time a process is
using the CPU.
►
It refers to the fraction of time the CPU is
processing instructions.
The difference between CPU utilization
and CPU efficiency is that CPU utilization
is the fraction of time when the CPU is not
idle while CPU efficiency is the amount of
time when the CPU is computing
instructions.

Code Optimization & Performance Tuning using Intel VTune
Some standard metrics to measure the processor
performance are:
Instructions retired
Clock Cycles Per instruction Retired (CPI)
Percentage of floating-point instructions
Measuring Processor Performance (Contd.)
►
This metric reports the number of instructions that are retired
during program execution.
When the execution of the instructions is complete, the
processor does not require the instructions any longer.
Thus, when the processor discards these instructions, they
are said to be retired.
►
CPI is the ratio of the number of clock cycles to the number of
instructions retired.
It is a measure of a processor's internal resource utilization. A
high value indicates low resource utilization.
This metric measures the percentage of retired floating-point
instructions.
A high percentage of floating-point instructions indicate that
the program is using only a specific resource while other
resources are idle.

Code Optimization & Performance Tuning using Intel VTune
The performance of a processor also depends on how fast
data can be read from and written to the main memory.
Memory speed is considerably slower than processor
speed.
The difference in the speeds of the processor and the
memory affects application performance.
In spite of computers with better processing power, the
impact of processor speed on the performance of
applications is not substantial.
The solution is to minimize the mismatch between the
processor and memory speeds.
To optimize application performance, it is important to
understand the memory hierarchy on a computer and the
performance of different components of the memory.
Examining Memory Specifications

Memory Hierarchy
The following figure shows the memory hierarchy on a
computer system.
► Registers speed up the execution
of instructions by providing fast
access to intermediate values
computed during a calculation.► This is the lowest level of cache
memory, which is faster and
smaller
► It is larger in size but slower
than the L1 cache
► It is slower and cheaper than
cache memory but faster and
more expensive than virtual
memory.
It is measured in megabytes.
►
The processor cannot directly
access virtual memory.
When data referenced by a
virtual address is requested, the
virtual address is translated to a
main memory address
13. Slide 13 of 23

What is the purpose of cache memory?
Answer:
Cache memory reduces the mismatch in the speeds of the
processor and the main memory.
14. Slide 14 of 23
Code Optimization & Performance Tuning using Intel VTune
When executing an instruction, the processor waits for the
data to be fetched from the memory.
The processor cannot execute any other instruction while
waiting because the previous instructions are loaded into
registers.
To achieve optimal performance, you must store the data as
near as possible to the processor so that the processor is
not idle.
This helps to reduce the time utilized for memory access
and improve processor utilization.
Understanding Memory Performance
15. Slide 15 of 23
Code Optimization & Performance Tuning using Intel VTune
Understanding Memory Performance (Contd.)
You can calculate the time taken for memory access by
knowing the hit and miss ratios.
The hit ratio is the number of times required data is available to
the total number of times data is requested from memory.
The miss ratio is the number of times data is not found to the
total number of times data is requested from memory.
16. Slide 16 of 23
Code Optimization & Performance Tuning using Intel VTune
To improve the performance of memory, you should ensure
that the data that the processor requested is at the nearest
location.
For this, you must be able to predict which data the
processor will reference.
This can be accomplished using the principle of locality of
reference.
The two types of locality of reference are:
Spatial locality
Temporal locality
Understanding Memory Performance (Contd.)
► Memory locations near each other
are usually used together.
If a program accesses a particular
memory location, it might soon
access a nearby memory location.
This location is called spatial
locality.
► If a program accesses a particular
memory location, it might soon
access the same memory location.
This location is called temporal
locality.
17. Slide 17 of 23
Code Optimization & Performance Tuning using Intel VTune
Some of the issues that affect memory performance are:
Cache compulsory loads
Cache capacity loads
Cache conflict loads
Cache efficiency
Data alignment
Software prefetch
Analyzing Issues Affecting Memory Performance
► When the required data is not found
in the cache, it has to be loaded in
the cache. This is known as a
cache compulsory load.
This occurs when the data is
loaded for the first time in the
cache.
► At times, the cache has to remove
recently used data to accommodate
other data requested by the
processor.
This is because, the capacity of the
cache is limited.
► Cache conflict loads occur if the
processor accesses five or more
units of data that use the same row.
You can avoid cache conflict loads
by changing memory alignment,
using registers for holding data, or
using algorithms that use fewer
regions of memory.
► Cache efficiency is the ratio of data
loaded into the cache to the data
used.► Data alignment is the organization
of data in memory.
Effective data alignment can
improve cache efficiency.
► Software prefetch enables a
processor to load a specific location
of memory before it is required for
processing.
As a result, the time taken for reads
and writes is reduced by the
amount of time that is saved while
the data is being loaded in the
cache.
18. Slide 18 of 23
Code Optimization & Performance Tuning using Intel VTune
A benchmark is a standard that is used for comparison.
In terms of application performance, you can consider
processor and memory benchmarks.
To arrive at a specific benchmark, you can use tests to
compare the performance of hardware and software running
a specified workload.
If you use graphic applications, a benchmark that tests
graphics speed might be useful.
Benchmarking
19. Slide 19 of 23
Code Optimization & Performance Tuning using Intel VTune
The different types of benchmarks are:
Single stream benchmarks
Throughput benchmarks
Interactive benchmarks
Benchmarking (Contd.)
► Single stream benchmarks
measure the time taken by the
computer to execute a collection of
programs.
► Throughput benchmarks
benchmark processor performance
for several jobs or a mix of codes
running simultaneously.
► Interactive benchmarks benchmark
the components of a computer such
as input/output system, operating
system, and networks.

Code Optimization & Performance Tuning using Intel VTune
In this session, you learned that:
Application performance is closely related to hardware
resources, such as processors and memory.
Processor speed is measured in clock cycles per second. This
is an indication of the number of instructions executed in unit
time.
Pipelining is an approach used for high-performance
computing to obtain maximum processor output.
The execution process of an instruction consists of CPU and
memory bursts.
A processor contains different functional units for executing
memory, integers, and floating-point instructions.
Summary
23. Slide 23 of 23
Code Optimization & Performance Tuning using Intel VTune
Processor performance can be measured in terms of branch
mispredictions, loads/stores complete, throughput, turnaround
time, instruction execution time, program execution time,
waiting time, response time, CPU utilization, and CPU
efficiency.
Computer memory consists of registers, cache memory, main
memory, and virtual memory.
The performance of memory depends on the speed of the
memory.
Cache compulsory loads, cache capacity loads, cache conflict
loads, data alignment, and the software prefetch capability
affect memory performance.
Performance benchmarking is the process of defining
standards for application performance in terms of processors
and memory.
