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...
指令集架构(ISA:Instruction Set Architectures) 为什么有ISA为了更好的控制计算机科学的复杂度,人们需要在不同层次间抽象出接口,以提高系统的迭代效率。指令集架构就是其中非常典型的例子,它是软硬件间的结构抽象。 现就其最本质而言,… 改名机会要过期 Computer Architecture —— ISA 指令集架构介绍 (一):为什么需...

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 ...
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 ...
Central Processing Unit (CPU) -Often referred to as the "brain" of the computer, the CPU executes instructions, performs calculations, and manages data. Its architecture dictates factors such as instruction set, clock speed, and cache hierarchy, all of which significantly impact overall system perf...
