WebLast time we saw a MIPS single-cycle datapath and control unit. Today, we’ll explore factors that contribute to a processor’s execution time, and specifically at the performance of the single-cycle machine. Next time, we’ll explore how to improve on the single cycle machine’s performance using pipelining.
