Question

Write a program for a 2-bit multiplier in assembly language. Also, multiple 01 and 10 and show the output in the program. Review the pipeline table and suggest changes to improve the performance.
Output: Assembly language code with screenshot of the output. Also mention/highlight the cycle count for the complete program. The cycle count should be optimized for performance improvement. Also, display pipeline table with 3-4 suggestion for improvements

Answer 1

.data
        mult1 dw 2521H
              dw 3206H
        mult2 dw 0A26H
              dw 6400H
        ans   dw 0,0,0,0

.code
        mov ax,@data
        mov ds,ax

;       LEA SI,ans

        mov ax,mult1
        mul mult2
        mov ans,ax
        mov ans+2,dx

        mov ax,mult1+2
        mul mult2
        add ans+2,ax
        adc ans+4,dx
        adc ans+6,0

        mov ax,mult1
        mul mult2+2
        add ans+2,ax
        adc ans+4,dx
        adc ans+6,0

        mov ax,mult1+2
        mul mult2+2
        add ans+4,ax
        adc ans+6,dx

        mov ax,4C00h
        int 21h
