RISC and CISC

Introduction
RISC and CISC stand for two different competing philosophies in designing modern computer architecture. The debate between them has been going on for a long time and will likely Continue. The difference between RISC and CISC can lays on many levels, lots of plausible arguments are put forward by both sides, such as code density, transistor counts, memory Bottlenecks, compiler and decode complexity etc.
The experiment is mainly based on the MIPS R2000 and Intel 80386 instruction sets, MIPS R2000 is a typical product of pure RISC while Intel 80386 is a typical kind of pure CISC chip.
The RISC
The term RISCs stands for Reduce Instruction Set Computers . It was originally introduced as a notion to mean architectures that can execute as fast as one instruction per clock cycle . RISC started as a notion in the mid-1970s and has eventually led to the development of the first RISC machine , the IBM 801 minicomputer . The launching of the RISC notion announces the start of a new paradigm in the design of computer architectures . This paradigm promotes simplicity in computer architecture design . In particular , it calls for going back to basics rather than providing extra hardware support for high-level languages . The RISC approach calls for enhancing architectures with the resources needed to make the execution of the most frequent and the most time-consuming operations most efficient.
