Please answer allquestions and show work. (Intro to Computer Architecture.)

Refer to the following table for the data required.

				Arith			Store			Load			Branch
	Instructions for a program			500			50			100			100
	CPI			1			5			5			2

A.) Calculate execution time of a program on a 2 GHz processor.

B.) Find global CPI of the program.

C.) If number of load instructions can be reduced by one-half, what is the speed up and CPI?

D.) If number of store and arithmetic instructions can be reduced by one-half, what is the speed up

and CPI?
