The following table shows the number of instructions for a program Artihmetic/Logic Load Store Branch Jump Total 580 144 75 26 900 (a). Assuming that arithmetic and logic instructions take 1 cycle, load and store take 6 cycles each, and branches and jumps 3 cycles each, what is the execution time of this program in a 2.9 GHz processor? b). What is the CPI for the program? (c). If the number of load instructions can be reduced by one third, what is the speedup and the new CPI? (d). If the number of jump instructions is doubled, is the resulting reduction in speed and the new CPI
