Question 1 Discuss four (4) factors which contribute to increase the speed of program executions of a computer. (a) (b) (8 marks) A program contains 1 billion instructions to be executed on a processor operating at 2 GHz. 50% of the instructions execute in 3 clock cycles, 30% execute in 4 clock cycles and 20% execute in 5 clock cycles. Determine the execution time for this program. { (6 marks) Suppose the microprocessor in (b) is redesigned so that all instructions that initially executed in 5 cycles now executed in 4 cycles. Determine the new clock rate of the microprocessor. (6 marks) [20 marks]
