You are asked to write a microprogram (similar to the one shown on the micro-architecture handout) to realize multiplying two 7-bit binary numbers (assume they are positive numbers) that are already stored in register A and B, and store the results in registers C and D. You are limited to the capability of the micro-architecture handout (assume 8-bit machine, all registers, and ALU being 8-bit, and shifter DOES NOT have left_out or right_out).

Your multiplication microprogram must include the following two input examples (for A and B) and the multiplication results (C and D).

A := 1011010 B := 1100110

A := 1101111 B := 1000001

At each step(line) of your micro-code, the values of the all the registers that you have used must be clearly presented.

You are can use any of the 16 provided registers in the micro-architecture handout (if needed).

A := 1101111

B := 1000001
