A pipelined processor has a clock rate of 5 GHz and exccutes a program with 5 million instructions. The pipeline has four stages, and instructions are issued at a rate of two per clock cycle. Ignore penalties due to branch instructions and out-of-sequence exccutions. a. What is the speedup of this processor for this program compared to a non-pipelined 2. processor? What is the throughput (in MIPS) of the pipelined processor? b
