4.1.3 [10] <4.1> Which resources (blocks) produce outputs, but their outputs are not used for this instruction? Which resources produce no outputs for this instruction?
Different execution units and blocks of digital logic have different latencies (time needed to do their work). In Figure 4.2 there are seven kinds of major blocks. Latencies of blocks along the critical (longest-latency) path for an instruction determine the minimum latency of that instruction. For the remaining three problems in this exercise, assume the following resource latencies:
