3. Let's compare a CISC machine versus a RISC machine on a standard program. Assume the following characteristics of the two machines. CISC: CPI of 6 for load/store, 3 for ALU and 7 for branch, CPU clock rate of 3.5 GHz RISC: CPI of 1.2 and a CPU clock rate of 1.75 GHz Since the CISC machine has more complex instructions, the Instruction Count (I) for the CISC machine is 25% smaller than the Instruction Count (I) for the RISC machine The standard program has a breakdown of 38% loads, 10% stores, 35% ALU operations, and 17% branches. Which machine will run the standard program in less time and by how much? 10 3. Let's compare a CISC machine versus a RISC machine on a standard program.

Answer rating: 100% (QA)

To solve the problem we need to calculate the total execution time for the standard program on each machine This can be done by determining the averag... View the full answer
