Chapter 10, Problem 49E

Program Plan Intro

Given data:

It is given that the program is loaded at starting address and it is given as $\text{A=30215}$ in the main memory.

Assumption:

Let take the starting address of application program as “A” and logical address as “L”.

• The physical address for the corresponding logical address “L” can be determined by adding the starting address “A” with the logical address “L”.
• The following is the diagrammatic representation of main memory to calculate the physical address.

Formula to calculate the physical address:

The physical address for the corresponding logical address is determined using the following formula,

$\text{Physical address }=\text{ L }+\text{ A}$        (1)

From the above formula,

• “L” represents “logical address”
• “A” represents “starting address”

Explanation of Solution

b.

Calculation of physical address for logical address “2302”:

The physical address for the logical address “2302” is determined using the formula from Equation (1).

Substitute logical address “L” value as “2302” and starting address “A” value as “30215” in Equation (1)...

Explanation of Solution

c.

Calculation of physical address for logical address “7044”:

The physical address for the logical address “7044” is determined using the formula from Equation (1).

Substitute logical address “L” value as “7044” and starting address “A” value as “30215” in Equation (1)...
