C952 Computer Architecture Extended Moore's Law states that integrated circuit resources double every 18-24 months Pipelining Moves multiple operations through hardware units that each do a piece of an operation. A means of introducing parallelism into the essentially sequential nature of a machine-instruction program. Systems software provides services that are commonly useful, including operating systems, compilers, loaders, and assemblers. Operating System (OS) Super...

Start LDA one OUT LDA zero OUT LDA count SUB one STA count BRP start HLT One DAT 1 Zero DAT 0 Count DAT 3 Explain, giving an example, how pipelining in a CPU could speed up the execution of this program. ( 3 marks ) An instruction can be fetched as the previous one is being decoded and the one before that is being executed.E.g. LDA zero can be fetched, while OUT is being decoded and LDA start one is being executed. Describe one issue the line BRP start may cause for a CPU usin...
