This document discusses organization architecture from different perspectives. It describes the users' need to understand functions at a high level, while programmers need to know how instructions are implemented. Designers need to understand both how instructions are implemented as well as how hardware components like the CPU, memory, and data path work together. It provides the example of a multiplier function and describes the core components of a CPU including the ALU. The document also discusses different types of codes like machine code, mnemonic code, and different programming languages as well as the role of translators in converting between codes.

2. Organization Architechture
 Users’ point of view
 need to know set of
Instructions in the functions
 Programmers’ perspective
 Softwares’
 Designers’ point of view
 Need to know how the
Instructions are Implemented
 Designers’ perspective
 Hardwares’
Eg : MULTIPLIER (function)

3. CPU

(Aids memory of User
Eg : SUB,DIV)

7. TRANSLATOR-Program to translate
from one code to another
Different types : depending on from
which code to which code the
Translation is done
FORTRAN
PASCAL
BASIC
M/C Code
Assembler Code
HLL Code(Statement in language)
