Direct memory access
This document discusses different types of data transfer modes between I/O devices and memory, including programmed I/O, interrupt-driven I/O, and direct memory access (DMA). It explains that DMA allows I/O devices to access memory directly without CPU intervention by using a DMA controller. The basic operations of DMA include the DMA controller gaining control of the system bus, transferring data directly between memory and I/O devices by updating address and count registers, and then relinquishing control back to the CPU. Different DMA transfer techniques like byte stealing, burst, and continuous modes are also covered.
8086 micro processor
The Intel 8086 is a 16-bit microprocessor that can access up to 1 MB of memory. It has two main components: the Bus Interface Unit (BIU) handles bus operations like instruction fetching and memory access, while the Execution Unit (EU) decodes and executes instructions. The BIU contains registers for the code, data, extra, and stack segments as well as an instruction queue. The EU has registers for accumulation, base, count, data, pointers, and flags, and contains an ALU and decoder. It executes instructions from the queued bytes using a pipeline architecture.

Ring Counter.pptx
This document describes a ring counter circuit using D flip-flops. A ring counter consists of flip-flops connected in a loop such that a single '1' circulates around the flip-flops as long as a clock signal is applied.

Bit pair recoding
Bit-pair recoding is a technique that halves the maximum number of additions needed for multiplication by recoding the multiplier bits into pairs. It works by selecting the multiplicand (the number being multiplied) based on the values of bit pairs in the multiplier. For each bit pair, the selection table indicates which multiplicand (the regular value or the negative value) to use. This allows multiplication to be performed with only n/2 additions, where n is the number of bits in the multiplier.

Common datapaths include load/store which uses memory addressing and branch/jump which uses instruction addressing. The ALU performs operations like addition and subtraction. The main control unit identifies instruction fields and controls the datapath. Multiplication can be done with combinational or sequential circuits while division similarly uses subtraction and shifting. Floating point uses separate exponent and mantissa fields.

Frequency transformation
This document discusses frequency transformations that can be used to design bandpass, bandstop, and high-pass filters based on a low-pass filter design. It explains that filters can be transformed from low-pass to other types by applying a suitable frequency transformation. Common transformations include applying substitutions to move the cutoff frequency or replace the frequency variable to transform the response from low-pass to high-pass. The transformations allow filters to be designed by first specifying a normalized low-pass filter and then transforming it.
Decimation and Interpolation
This document provides an overview of decimation and interpolation in multirate signal processing. It discusses downsampling by an integer factor M, which reduces the sampling rate by taking every M-th sample and discarding the rest. Downsampling can cause aliasing if the signal is not bandlimited, so a low-pass filter is used beforehand. The document also covers properties like linearity and time-variance, identities for cascading systems, and polyphase decomposition to more efficiently implement decimation filters when the number of coefficients is a multiple of the decimation factor. Examples and illustrations are provided using MATLAB code.

It represents the sequence of micro-operations performed on binary information stored in registers and the control that initiates the sequences. A register is a group of flip-flops that store binary information. Information can be transferred between registers using replacement operators and control functions. Common bus systems using multiplexers or three-state buffers allow efficient information transfer between multiple registers by selecting one register at a time to connect to the shared bus lines. Memory transfers are represented by specifying the memory word selected by the address in a register and the data register involved in the transfer.

The document then discusses various microoperations including arithmetic operations like addition and subtraction, as well as incrementing and decrementing registers. It also covers transferring data to and from memory and constructing common bus systems using multiplexers or three-state buffers to transfer data between multiple registers.

bus and memory tranfer (computer organaization)
A bus system is an efficient way to transfer data between registers in a computer. It uses a set of common lines that can selectively connect one register at a time to allow its information to be transferred. One way to construct a bus system is by using multiplexers. For example, a 4-bit system with 4 registers would use 4 multiplexers, each with 3 inputs to selectively connect the bits of one register to the common 4-line bus. Control signals on the multiplexer selection lines determine which register is connected to the bus at any given time.

Instruction FormatMachine instruction has an opcode and zero or m.pdf
Instruction Format:
Machine instruction has an opcode and zero or more operands. Architectures are differentiated
from one another by the number of bits allowed per instruction (16, 32, and 64 are the most
common), by the number of operands allowed per instruction, and by the types of instructions
and data each can process. More specifically, instruction sets are differentiated by the following
features:
• Operand storage in the CPU (data can be stored in a stack structure or in registers) • Number of
explicit operands per instruction (zero, one, two, and three being the most common)
• Operand location (instructions can be classified as register-to-register, register-to-memory or
memory-to-memory, which simply refer to the combinations of operands allowed per
instruction)
• Operations (including not only types of operations but also which instructions can access
memory and which cannot) • Type and size of operands (operands can be addresses, numbers, or
even characters)
The following are some common instruction formats:
• OPCODE only (zero addresses)
• OPCODE + 1 Address (usually a memory address)
• OPCODE + 2 Addresses (usually registers, or one register and one memory address)
• OPCODE + 3 Addresses (usually registers, or combinations of registers and memory)
Instruction Length:
The traditional method for describing a computer architecture is to specify the maximum number
of operands, or addresses, contained in each instruction. This has a direct impact on the length of
the instruction itself. Instructions on current architectures can be formatted in two ways: • Fixed
length-Wastes space but is fast and results in better performance when instruction-level
pipelining is used, as we see in Section 5.5. • Variable length-More complex to decode but saves
storage space.
Memory organization affects instruction format. If memory has, for example, 16 or 32-bit words
and is not byte-addressable, it is difficult to access a single character. For this reason, even
machines that have 16-, 32-, or 64-bit words are often byteaddressable, meaning every byte has a
unique address even though words are longer than 1 byte.
COMMON BUS Structure:
The basic computer has eight registers, a memory unit, and a control unit. Paths must be
provided to transfer information from one register to another and between memory and registers.
The number of wires will be excessive if connections are made between the outputs of each
register and the inputs of the other registers. A more efficient scheme for transferring
information in a system with many registers is to use a common bus. It is known that how to

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
