Chapter 9, Problem 4E

Explanation of Solution

Explanation:

The number of global registers for different functions is 10

The number of local registers for different functions is 10

The number of input parameter registers is 6

The number of output parameter registers is 6

The size of the register window can be calculated using the following formula

$\begin{array}{c}\text{Size}\text{of}\text{register}\text{window}\text{=}\text{Number}\text{of}\text{global}\text{registers}\\ \text{+}\text{Number}\text{of}\text{local}\text{registers}\\ \text{+}\text{Number}\text{of}\text{input}\text{parameter}\text{registers}\\ \text{+}\end{array}$
