Chapter 9, Problem 5E

Explanation of Solution

Explanation:

The number of global registers for different functions is 8.

The number of local registers for different functions is 8.

The number of input parameter registers is 4.

The number of output parameter registers is 4.

The total number of local registers can be calculated using the following formula,

$\text{Total}\text{number}\text{of}\text{local}\text{registers}\text{=}\text{Number}\text{of}\text{local}\text{registers}\text{in}\text{each}\text{window}\text{×}\text{Number}\text{of}\text{windows}$

Substitute, “8” for “number of local registers in each window” and “10” for “number of windows” in the above formula,

$\begin{array}{c}\text{Total}\text{number}\text{of}\text{local}\text{registers}\text{=}\text{8}\text{×}\text{10}\\ \text{=}\text{80}\end{array}$

Thus, the total number of local registers is 80.

The total number of common registers can be calculated using the following formula,

$\text{Total}\text{number}\text{of}\text{common}\text{registers}\text{=}\text{Number}\text{of}\text{common}\text{registers}\text{in}\text{each}\text{window}\text{×}\text{Number}\text{of}\text{windows}$

Substitute, “4” for “number of common registe
