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 interfacing topics and Part VII introduces advanced architectures. Show moreBehrooz Parham...
Computer architecture taxonomy.In 1966, Michael Flynn proposed a taxonomy of computer architectures based on the number ofconcurrent instructionsand the number ofdata streams:SISD(Single Instruction, Single Data);SIMD(Single Instruction, Multiple Data); and MIMD (Multiple Instructions, Multiple Data). ...
Reduced Instruction Set Computer (RISC) Architecture is a processor design approach that focuses on a minimal set of simple instructions to enhance performance and efficiency in computing systems. AI generated definition based on: Rapid System Prototyping with FPGAs, 2006 ...
一般来说,Prefetching 在指令缓存(Instruction Cache)里很好用,因为通常情况下执行的指令都是按照顺序的,方便预测。并且,可以用于一级指令缓存(Instruction L1 Cache) 和二级缓存之间,因为是片上系统,可以充分利用带宽。反之,这个机制不用于二级缓存和内存之间,因为一般情况内存都不在片上(Off-Chip),中间的带宽十分昂贵。
是由它的下一层级,算法(Algorithm)构成的。算法也依赖于所实现它的编程语言(Programming Language),然而编程语言也需要操作系统(Operating System)的支持才能正确工作。那什么东西支持操作系统呢?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)。

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...
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 ...
processes the instruction by performing calculations or logical operations, and then outputs the result. This process is aided by various subcomponents like ALU (Arithmetic Logic Unit) for calculations, registers for holding data, and the control unit for managing the process. The speed and efficienc...
