Suppose we have two implementations of the same instruction set architecture executing $2\backslash$times $106$ instructions. Computer A has a $10$ GHZ clock and a CPI of $2\mathrm{.}0$ a program, and computer B has a $5$ GHZ clock and a CPI of $1\mathrm{.}2.$ a$.$ How many clock cycles each computer execute? b$.$ What is the execution time of each processor? c$.$ What is the MIPS rating of each processor? d$.$ Which processor is a better processor? Why?
