This is introduction to micro processor and assembly language course. In this chapter you are going to be introduced to basic idea of microprocessor. Language hierarchy and virtual machine concept.
When a human programmer develops a set of instructions to directly tell a microprocessor how to do something
They’re programming in the CPU’s own “language” This language, which consists of the very same binary codes which the Control Unit inside the CPU chip decodes to perform tasks, is often referred to as machine language.
it is often written in hexadecimal form, because it is easier for human beings to work with. For example, I’ll present just a few of the common instruction codes for the Intel 8080 micro-processor chip.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Procedure, Macro, Array, String (???)
5. DESIGN OBJECTIVES OF MP
Maximize Performance
Speed of operation: How quickly an operation can be completed
Throughput: No of operations completed in unit time, not necessarily
the same as speed, consider Servers.
Maximize Productivity
Interface provided must be easy
Be one step ahead of market needs and two steps
ahead of competition
7. DESIGN CONSTRAINT
Power consumed
Today’s processors consume a peak power of 100 W, which means a
peak current of nearly 80A.
Area
Cost
Backward compatibility
Windows running on Intel P3 Processor should run on Intel P4 too.
Time taken to design the processor should not be
very large or else the competitor may get ahead
Other factors like security, scalability, reliability also
need to be considered in processor design
8. MARKET
Desktop
Processor for desktop computers. Cost, backward compatibility are very
important. Eg: Intel Pentium, AMD Athlon
Servers
Processor for applications requiring huge amount of computation, data
handling like web servers, database servers, scientific computation
servers. In general, multiple processors are used. Throughput is a very
important metric for servers in general. Eg: Google servers, vsnlproxy
Embedded
For applications in electronic appliances, robots, cars, mobiles etc. Power
consumption, cost are very important metrics. Eg: Microcontrollers like
8051, PIC, specifically designed processors for cars, mobiles etc.

18. ASSEMBLY AND MACHINE LANGUAGE
Machine language
Native to a processor: executed directly by hardware
Instructions consist of binary code: 1s and 0s
Assembly language
Slightly higher-level language
Readability of instructions is better than machine
language
One-to-one correspondence with machine language
instructions
Assemblers translate assembly to machine code
Compilers translate high-level programs to
machine code
Either directly, or
Indirectly via an assembler
21. INSTRUCTIONS AND MACHINE LANGUAGE
Each command of a program is called
an instruction (it instructs the
computer what to do).
Computers only deal with binary data,
hence the instructions must be in
binary format (0s and 1s) .
The set of all instructions (in binary
form) makes up the computer's
machine language. This is also
referred to as the instruction set.
22. INSTRUCTION FIELDS
Machine language instructions usually are made up of
several fields. Each field specifies different
information for the computer. The major two fields
are:
Opcode field which stands for operation code and it
specifies the particular operation that is to be
performed.
Each operation has its unique opcode.
Operands fields which specify where to get the source
and destination operands for the operation specified
by the opcode.
The source/destination of operands can be a constant, the
memory or one of the general-purpose registers.
24. TRANSLATING LANGUAGES
English: D is assigned the sum of A times B plus 10.
High-Level Language: D = A * B + 10
Intel Assembly Language:
mov eax, A
mul B
add eax, 10
mov D, eax
Intel Machine Language:
A1 00404000
F7 25 00404004
83 C0 0A
A3 00404008
A statement in a high-level language is translated
typically into several machine-level instructions
25. ADVANTAGES OF HIGH-LEVEL LANGUAGES
Program development is faster
High-level statements: fewer instructions to code
Program maintenance is easier
Programs are portable
Contain few machine-dependent details
Can be used with little or no modifications on
different machines
Compiler translates to the target machine
language
However, Assembly language programs are not
portable
26. VIRTUAL MACHINE CONCEPT
An effective way to explain how a computer’s hardware
and software are related is called the virtual machine
concept.
A computer can usually execute programs written in its
native machine language. Each instruction in this
language is simple enough to be executed using a
relatively small number of electronic circuits. For
simplicity, we will call this language L0.
Programmers would have a difficult time writing
programs in L0 because it is enormously detailed
and consists purely of numbers. If a new language,
L1 , could be constructed that was easier to use,
programs could be written in L1. There are two ways
to achieve this:
27. Interpretation:
As the L1 program is running, each of its
instructions could be decoded and executed
by a program written in language L0. The L1
program begins running immediately, but
each instruction has to be decoded before it
can execute.
Translation:
The entire L1 program could be converted into
an L0 program by an L0 program specifically
designed for this purpose. Then the resulting
L0 program could be executed directly on the
computer hardware.
28. Virtual Machines
Rather than using only languages, it is easier
to think in terms of a hypothetical computer,
or virtual machine , at each level. we can
define a virtual machine as a software
program that emulates the functions of some
other physical or virtual computer.
The virtual machine VM1 , can execute
commands written in language L1. The
virtual machine VM0 can execute commands
written in language L0.
Each virtual machine can be constructed of
either hardware or software.
29.
30. WHY LEARN ASSEMBLY LANGUAGE?
Two main reasons:
Accessibility to system hardware
To use space and time efficiently
Some application of assembly languages
are:
Real time system. E.g Traffic control system
Embedded system. Where there is no
compiler. E.g Micro chips.
Operating system. Specially kernel part of
operating system. Where direct access of
hard ware is necessary.
31. ASSEMBLER
Software tools are needed for editing, assembling,
linking, and debugging assembly language
programs
An assembler is a program that converts
source-code programs written in assembly
language into object files in machine language
Popular assemblers have emerged over the years
for the Intel family of processors. These include
…
TASM (Turbo Assembler from Borland)
NASM (Netwide Assembler for both Windows and
Linux), and
MASM (Macro Assembler from Microsoft)
32. LINKER AND LINK LIBRARIES
You need a linker program to produce
executable files
It combines your program's object file
created by the assembler with other
object files and link libraries, and
produces a single executable program
LINK32.EXE is the linker program
provided with the MASM distribution
for linking 32-bit programs
