Discuss how different CISC instruction formats versus the fixed RISC instruction formats can complicate the design of an instruction data path. Discuss the effect of switching the positions of the execute and DM stages in Fig. 8.17. For the pipeline chart in Table 8.6, determine CPI for k = 10 iterations. Also, determine the lower bound for the CPI as k approaches infinity.
