WebThe other long path is similar, but goes through Control instead of Regs (to generate the control signal for the ALU MUX). A Control is faster than registers, so the critical path is I-Mem, Regs, Mux, ALU, Mux. B The two long paths are equal, so both are critical. One long path for LW instruction is to read the instruction , read registers ... WebCritical-path instructions, and their dependents, tend to get stalled in the instruction queue, and often become the oldest (bottom) instruction in the queue at some ... dictions are only used to schedule load instructions. 4 Methodology Table 1 summarizes the benchmarks used in all our sim-ulations.

WebSee Page 1. Clock cycle time is determined by the critical path for load instruction LW: I-Mem (read instruction), Regs (takes longer than Control), Mux (select ALU input), ALU, Data Memory, and Mux (select value from memory to be written into Registers). The latency of this path is 400 + 200 + 30 + 120 ps + 350 ps + 30 ps = 1130 ps 1430 ps ... WebFor example, instruction bits I[20-16] should be going into the Read register 2 and Write register. It's just that in the end, the Read data 2 is not being used due to the MUX selecting 1. Did my prof choose not to draw the red lines going to the Read register 2 path just to emphasize on the most WebThis portion takes place for all instructions.
