Summary
This document provides an overview of Instruction Set Architecture (ISA). It covers topics like instruction formats, addressing modes, and comparisons between CISC and RISC architectures, along with instruction sets. It also explores the differences between memory and register architectures in detail.

Instruction Set Architecture (ISA) An Instruction ISA is Vocabulary, what a processor can understand An Instruction Using PC, ACC, Gen. Purpose Registers, SP Instruction Set Architecture ISA Is Important; Not only from the programmer’s perspective From processor design and implementation perspective as well Instruction Set Architecture ISA Design Choices Implicit vs Explicit operands in instruction, operands location and addressing modes Classification of ISA Operands are in registers or in specific memory locations Evolution of ISA Register-memory are CISC Type Architecture Register-register are RISC type Architecture Classification of ISA Comparisons of Architecture Classification of Operations Instruction Format Addressing Modes Addressing Modes CISC Vs RISC Features of CISC Features of RISC Memory Vs Register Memory
