Types,Operands and  Addressing Modes After a brief introduction of ISA, here in this part of the series we’ll look at: Content:   Types of Operands  Instruction set design Types of Instructions Types of Addressing modes Types of Operands: Operands basically refer to the type of parameter which is passed on to, along with an instruction. It might be a : Register/Memory address Constant/Immediate Consider the following examples: ADD r1,r2,r3;      will add r2 and r3 and store it’s value in r1 Here, Operands is r1,r2 and r3. ALL of which are registers. ARM has in general 16 general purpose registers…

INTRODUCTION TO INSTRUCTION SETS I recently brought the ARM edition of the book Computer Organization and Design by Patterson and Hennessy from library. Half way through the book, I thought of sharing the content of this book in a more elaborated manner by making a series of tutorials on Arm Instruction Set.So, here’s part one of the series. Content Basic definitions Types of Instruction sets Architecture(ISA) General purpose register architecture Stack architecture Accumulator architecture Basic Definitions   Benchmarks:  A program selected for use in comparing computer performance.SPEC(System Performance Evaluation Cooperative) is such an effort supported by a number of vendors…
