Learning Computer Composition Principle ~ ~ Instruction system and performance

I did not learn the system before, the principle of computer composition, now only learning ~ ~

The first is the concept:

Command---The computer to perform some kind of operation. ---instruction

The instruction system----the set of machine instructions, also called the instruction set. Instruction Set.

CIS (Complex instruction system, Complex instruction Set), a computer with a complex instruction system is called a complex instruction system computer (CISC).

Only 20% are commonly used in CISC, resulting in a streamlined instruction system (ris--reduced instruction Set), a computer with RIS called a thin Instruction system computer (RISC).

Performance of the instruction system:

Completeness, effectiveness, regularity, compatibility, scalability
