4.3 If this ADD Rd, Rs, Rt is the only instruction to be supported by the processor, what is the clock cycle time (in ps)? Use the latency of each block below. 1-memory = 200 ps registers= 90 ps ALUmux = 20 ps Regmux = 20 ps ALU Data-memory = 250 ps = 90 ps 4.4. What is the clock rate in G Hz (giga Hertz) in 4.3?
