再往下一层就是我们今天的主角:指令集架构(Instruction Set Architecture, 以下简称ISA)。 从ISA 开始往下,都是和硬件电路相关的内容了,所以我们可以得出一个基本的定义:指令集架构是一个能为电路硬件翻译应用程序的一层抽象层。它能够为操作系统制定很多规则和约束,也能让编程者不用操心具体的电路结构,转而在这一...
代表有 MIPS16、ARM THUMB 等等 还有一种特殊的架构:超长指令集(Very Long Instruction Word,VLIW)是由英特尔和惠普共同在21世纪初提出的一种用于改善工作站性能的新型架构,里面的每条指令束(Instruction Bundle)是由四条或者更多的普通指令集合在一起而形成的。由于技术和时代原因,最后悄然退场,我们在后面也会专门开...

Instruction execution is facilitated by a sequence of macro and micro-operations (steps) by the control unit. The number such micro-operations required to complete an instruction depends on the instruction and the datapath. Please recall the topic "Datapath Functioning" in chapter 12, wherein we ...

Part II discusses instruction-set architecture. The next two parts cover the central processing unit. Part III describes the structure of arithmetic/logic units and Part IV is devoted to data path and control circuits. Part V deals with the memory system. Part VI covers input/output and ...
Computer Architecture的另一个名字是Trade-off。看着整个体系结构的发展历程中种种新技术的使用,无不体现了Trade-off的设计思想。硬件一直都是并行工作的,不管是pipeline, out-of-order, superscale, VLIW, Instruction Level Parallelism抑或是现在的Multicore,硬件的发展... (展开) 30 2回应 sosowo 2010-05-16...
