RISC(精简指令集计算机)和CISC(复杂指令集计算机)是当前CPU的两种架构.它们的区别在于不同的CPU设计理念和方法. 早期的CPU全部是CISC架构,它的设计目的是要用最少的机器语言指令来完成所需的计算任务.比如对于乘法运算,在CISC架构的CPU上,您可能需要 这样一条指令:MUL ADDRA, ADDRB就可以将ADDRA和ADDRB中的
The most common examples of CISC are x86 CPUs. 4.1. Advantages of CISC Architecture Since each instruction is complicated, fewer instructions can be utilized to implement a given task. It causes small code sizes. 4.2. Disadvantages of CISC Architecture ...
RISC vs. CISC processors Today's x86 processor designs are an amalgamation of features and functionality from the last 30 years, right up to today's Intel-VT and AMD-V instructions to support hardware-assisted virtualization. But there's a problem with this complex instruction set computing (CI...

2、CPU的基本工作:执行大量的指令。不同的CPUs 实现了不同的指令集,应用于特定CPU的指令集称为指令集架构,Examples:MIPS,arm,RISV -V... 3、CISC vs RISC: RISC philosophy keep the instruction set small and simple do complicated operations by composing simpler ones This went...
Although these facts make the CISC architecture seem irrelevant, inefficient and outdated, there are many advantages of CISC that can be understood through a brief look at real life examples of CISC and RISC, and it s various purposes. The most common example of CISC and RISC being used in ...
CISC-y RISC-ness An unusual type of processor from the early 2000s seemed to offer the best of all worlds—and may be the most inventive approach to the CPU ever developed. By Ernie Smith Apr 26, 2023 Filed under: cisc, computers, crusoe, David A.
参考译文:像许多RISC指令集(以及一些复杂的指令集计算机(CISC)指令集,如像许多RISC指令集(以及一些复杂的指令集计算机(CISC)指令集,如x86和IBM System / 360及其后代通过z / Architecture),RISC-V缺少写入寄存器的地址模式。例如,它不自动递增。[2]:24 RISC-V 管理 CPU 与 thread 之间的共享存储器的方式是确保...
