WitrynaConcepts of Pipelining. Pipelining increases the performance of the system with simple design changes in the hardware. It facilitates parallelism in execution at the hardware level. Pipelining does not reduce the execution time of individual instructions but reduces the overall execution time required for a program. Witryna28 lip 2024 · 1. To be able to improve CPI and the speed-up factor you need to enable the pipeline. The programmer can help improve CPI but it is best to leave that to an optimising compiler and clever CPU architecture.
