Question $2$ continued

$($c$)$ Power and energy considerations are important in the design of modern electronic devices. You are asked to compare two processors labelled A and B$.$

Processor A consumes $(0\mathrm{.}6+\frac{U}{9})$ times the power of processor B but finishes a particular task in $(20-2U)\%$ less time.

Justify which processor would you choose

$($i$)$ if you were constrained solely by power delivery considerations?

$($ii$)$ if you were trying to minimize response times?

$($iii$)$ if you were trying to minimize the energy consumed per operation?

$($d$)$ You are asked to design a SRAM array consisting of $128$ rows and $64$ columns. How many logical words will be stored for a word size of $32$ bits. How many address bits will be required for the row decoder and the column decoder?
