Essay: Architecture of a Processor

Sample Essay

As the discussion is on for enhanced performance of processors using cache and registers, another approach is pointing towards the architecture of a processor. RISC or Reduced Instruction Set Architecture used large on-chip caches and increased number of processor registers reducing the number of instructions with a degree of magnitudes.

The procedure of manipulations is the data decoded and processed by storing them on registers. Two instructions hold the right of changing or forwarding the data and circulating it between memory and registers. This approach was found to be pretty simple in a sense that all the operations have to be passed through any of these instructions only and none else making the code easier limiting the instruction set. There has been a fixed length defined for execution in the pipeline but with the reduced instruction set architecture the instructions used to be examined and some of them are executed in parallel and almost hardwired control unit (Bramer).
