Apollo的PRISM (Parallel Reduced Instruction Set Microprocessor):专为 Apollo 的 DN10000 工作站提供动力。 CISC 的消亡? 也许与所有新的 RISC 设计一样值得注意的是,新的 CISC 架构将变得罕见。 20 世纪 70 年代末出现了英特尔 8086、摩托罗拉 68000、国家半导体 32016,以及德州仪器 (Texas Instruments) 和几家...
Intended for both engineers and managers who are given the task of selecting an architecture or design approach, this book examines the developments of Motorola's CISC, RISC and DSP processors. It describes the typical system configurations and engineering trade-offs that are made. The text ...
of the CPU. We’ve briefly given information about the RISC and CISC architecture. We’ve shared the advantages and disadvantages of both design choices.In recent days, since the ARM is proprietary, RISC-V comes on the stage and starts to change the market share in microprocessor architectures...
这也是笔者对随处可见只要将CISC 指令『转译』成看起来很像RISC 的微指令，即可迎刃而解指令集复杂度带来的诸多问题之类论调，长期嗤之以鼻的主因。如此夸张的复杂度一路叠床架屋，没剩多少可塞入cache存储器的空间，不仅让延迟至1981 年才问世的iAPX 432 难以单一芯片化，像主要运算单元（General Data Processor...
A Reduced Instruction Set Computer is a type of microprocessor architecture that utilizes a small, highly-optimized set of instructions rather than the highly-specialized set of instructions typically found in other architectures. RISC is an alternative to the Complex Instruction Set Computing (CISC) ...

1 Introduction Interesting debates on CISC and RISC instruction set architecture styles were fought over the years, e.g.: the Hennessy-Gelsinger debate at the Microprocessor Forum [8] and Bhandarkar publications [3, 4]. In the Bhandarkar and Clark study of 1991 [3], the comparison was ...
risc是精简指令集计算机，cisc是复杂指令集计算机，相对于cisc，risc的这个“精简”体现在三个地方：定长...
(甚至连垃圾回收机制和透过硬件实作的型别检查都有了) 和定址模式等,英特尔还发展由Ada 语言撰写的iMAX 432 操作系统,结果英特尔就创造了”最CISC(复杂指令集电脑)的CISC”,指令编码长度别说极度不固定了,竟然还可以6~321Bits(你眼睛绝对没看错,是位元,不是位元组),连1~17Bytes 的x86 和1~54Bytes 的DEC ...
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.
