Instruction Set Architecture in Computer Architecture

Instruction Set Architecture:

Manufacturers of CPUs publish a document that contains information about the processor such as a list of registers, a function of each register, the size of the data bus, the size of the address bus, and a list of instructions that can be executed by the CPU. Each CPU has a known instruction set that a programmer can use to write assembly language programs. Instruction sets are specific to each type of processor. Pentium processors use a different instruction set than ARM processors. The instructions classified are based on several operands or types of operation.
