关于CISC 和 RISC 地简述 一、基本概念 二、CISC 三、RISC 四、CISC 和 RISC 的比较 一、基本概念 指令系统朝着两个截然不同的方向发展: 一是增强原有指令的功能,设置更为复杂的新指令实现软件功能的硬化,这类机器称为复杂指令系统计算机(CISC),典型的有采用X86 架构的计算机; 二是减少指令种类和简化指令功能...
RISC vs CISC is a topic quite popular on the Net. Everytime Intel (CISC) or Apple (RISC) introduces a new CPU, the topic pops up again. But what are CISC and RISC exactly, and is one of them really better? This article tries to explain in simple terms what RISC and CISC are and...

CISC（复杂指令集）和RISC（精简指令集）是设计制造微处理器的两种不同思路的技术，虽然它们都是试图在...
如该报告最后一段所写:“显然数十年来的硬体与编译器研发,已经能有效掌握RISC与CISC架构,而且两者在未来诉求节能的创新应用中拥有平等地位。” 编译:Judith Cheng (参考原文: RISC vs CISC: What"s the Difference?,by Bernard Cole)

Let’s also look at the figure below to understand the difference between the RISC and CISC. It’s an example of multiplying two numbers in the memory: In the CISC approach, as we see in the figure, there is only one complex instruction “MULT”.It takes care of everything. It works...
using : CISC directly : add A,B,C so the question is since both patterns gave the same output at the end b+c will be stored in a , but the difference that # of used instructions , but why also the time complexity is not the same ( as I have mentioned above ( definition )...
RISC-V,ARM和x86微处理器之间的许多差异都很细微,与内存的寻址方式,分支的执行方式,异常的处理方式等等有关。本文将考虑更高级别的差异,并将简要比较精简指令集计算(RISC)和复杂指令集计算(CISC),考虑这…
春风亦如边鼓,催促着RISC-V备胎转正。然而四年过去,RISC-V似乎依然没走出备胎的困境。 合格的备胎 三大指令集中,x86为复杂指令集架构(CISC),Arm和RISC-V为精简指令集架构(RISC)。两者的区别顾名思义: CISC尽可能将任务一次性做完,高效但费脑(性能高、功耗大),RISC则是将任务拆解,分次做完,虽然对个人能力要求...
