# CS501 assignment no. 1 (SOLUTION)

Q1.

Part a: 15 marks

Write an SRC assembly language program to evaluate the following expression:

f = 4(k+32) + 16(g-h)

Solution:

Part b: 5 marks

Draw memory map table for the above program using the following scenario and assume that SRC uses 16-bit memory in this case.

.ORG  300      ; start the next line at address 300

k:         .DW                1          ;

g:         .DW                1          ;

h:         .DW                1          ;

f:          .DW                1          ;

.ORG 400       ; start the code at address 400

The code starts at address 400 and each instruction takes 16-bits in the memory.
