[Imran Jafery]

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.

Solution:

ld R1, g

kd R2, h

sub R3,R1,R2         ;R3 contains (g-h)

shl R4, R3, 4        ; R4 contains 16(g-h)

ld R5, K             

addi R6, R5, 32    ;R6 contains (k+32)

shl R7, R6, 2        ;R7 contains 4(k+32)

add R8,R7, R4     ; R8 contains 4(k+32)+16(g-h)

st R8, f            ; store the above result into memory location f
