Instruction Set

INSTRUCTION SET:

The instruction set also known as instruction set architecture (ISA).

ISA is part of a computer that related to machine language programming.

The instruction set provides commands to the processor, to tell it what it needs to do.

The instruction set consists of addressing mo0des, instructions, data types, registers,  memory architecture, interrupt, exception handling, external I/O, etc.

An example of an instruction set is the x86 instruction set, which is common to find on computers today.

Intel Pentium and AMD Athlon processors use nearly the same x86 instruction set.

Different computer processors can use almost the same instruction set while differ in internal design.

An instruction set can be built into the hardware of the processor as well as it can be emulated in software, using an interpreter.

The hardware design is more efficient and faster than the emulated software version.

Examples of instruction set

COMPARE – To compare numbers.

IN – To input information from a device, e.g. keyboard, scanners etc.

JUMP - Jump to designated RAM address.

JUMP IF - Conditional statement that jumps to a designated RAM address.

LOAD - Load information from RAM to the CPU.

OUT - Output information to device, e.g. monitor.

STORE - Store information to RAM.

ADD - Add two numbers together.
