1. For the instruction: IF-ICMPEQ offset A) Explain the purpose of each step of the following microprogram MAR SP SP -1 MAR SP SP -1 if icmpeq1 if_icmpeq2 if_icmpeq3 if_icmpeq4 if icmpeq5 if OPC TOS TOS MDR - B) Why do we need to temporarily copy TOS in OPC in cycle 4 and later use it for comparison in cycle 6 instead of doing the comparison in one cycle? 1.
