Question

CMPE 263-SPRING 2019-HW-3

Hint. For all the codes required, run them in the Basic Computer Simulator with two print screens, one shows code, registers, memory involved before run, and the second after run. Without them, the mark will reduce to ½.

Q3. Assume in locations A and B resides two 8 bit signed magnitudenumbers. Write an assembly subroutine code to multiply them and saves the result in C location. Start your code from 100. The code should be general for any sign of A and B numbers.

Try the code for A and B as positive and negative respectively, then, for both of them as negative numbers.

                        ORG    100

                        BSA     MUL

            A         HEX     0080

            B          HEX     1004

            C          HEX     0000
