Let us consider a computer executing the following mix of instructions:

Instruction Frequency (IC) Clock cycles (CPI) ALU 50 3 LOAD 20 6 STORE 10 6 BRANCH 10 4 JUMP 10 4

a) How much is the CPI average? b) How much is the Throughput expressed in MIPS, assuming a clock frequency of 2000 MHz? c) Let us assume that, given a hardware optimization technique, 40% of instructions of the program are executed with CPI

2 = 2.05 and the remaining fraction of instructions (60%) is executed with the same CPI

calculated in the case (a). How much is the overall Speedup due to CPI enhancement? How much is the new Throughput expressed in MIPS?
