William Faulker:「过去永远不会死,它甚至还没有过去。」 CISC 和 RISC 是 David Patterson 和 David Ditzel 在 1981 年正式提出的。四十年过去了,二者的发展有哪些融合与变迁?IT 新闻界资深人士 Joel Hruska 撰长文对该领域的发展史及其将面临的挑战做了详细阐述,以下是 ...
CISC(复杂指令集计算)和RISC(精简指令集计算)是两种不同的计算机指令集架构。 本文引用地址: 复杂指令集:CISC架构设计了大量的复杂指令,每条指令可以完成较为复杂的操作。 较少的指令数:因为每条指令可以完成较多的操作,所以总体的指令数较少。
关于RISC和CISC处理器的区别,大多数人会认为是一些特性、指令,或者是晶体管数量的差异。但实际上两者之间的差别不能简单的一概而论。 少量指令并不意味着RISC 首先,我们需要摒弃一些非常明显的误解。因为RISC的意思是简化指令集计算机(Reduced Instruction ...
如果你学习过X86微机原理和汇编语言,你可能会依稀地记得,我们在用汇编语言开发X86代码时,需要定义数据段,代码段,堆栈段和扩展段,这些段定义好之后,将会在写程序的时候有不同的用处。比如,当我们需要用到变量的时候,我们就需要将其定义到数据 ...
At WWDC, Apple announced a radical change to its computers. The company is dropping Intel as its CPU provider, and will be transitioning its laptops and desktops to custom Apple-designed chips over ...
Prompted by the chipmaker's announcement of the SSE5 instruction-set extensions, Glaskowsky analyzes the ultimate outcome to this old controversy. Peter N. Glaskowsky is a computer architect in ...
Back in 1998, when I first began covering hardware at the newly launched Ars Technica, much of my writing focused on issues raised by the raging Mac vs. PC flame wars that took place in computing ...
Try to investigate the differences between the x86 and ARM processor families (or x86 and the Apple M1), and you'll see the acronyms CISC and RISC. It's a common way to frame the discussion, but not a ...
