Question: 4.7 Problems in this exercise assume that the logic blocks used to implement a processor's datapath have the following latencies: "Register read" is the time needed after the rising clock edge for the new register value to appear on the output. This value applies to the PC only. "Register setup" is the amount of time a register's data input must be stable

4.7 Problems in this exercise assume that the logic blocks used to implement a processor's datapath have the following latencies: "Register read" is the time needed after the rising clock edge for the new register value to appear on the output. This value applies to the PC only. "Register setup" is the amount of time a register's data input must be stable before the rising edge of the clock. This value applies to both the PC and Register File. 4.7.1 $[5]<\$4.4>$ What is the latency of an $R$-type instruction (i.e., how long must the clock period be to ensure that this instruction works correctly)? 4.7.2 $[10]<\$4.4>$ What is the latency of $1w$ ? (Check your answer carefully. Many students place extra muxes on the critical path.) 4.7.3 $[10]<\$4.4⟩$ What is the latency of $5w$ ? (Check your answer carefully Many students place extra muxes on the critical path.) 4.7.4 $[5]<\$4.4⟩$ What is the latency of beq? 4.7.5 [5] $\ll \$4.4⟩$ What is the latency of an arithmetic, logical, or shift I-type (non-load) instruction? 4.7.6 [5] $⟨\$4.4⟩$ What is the minimum clock period for this CPU?
