Question

Translate the given MARIE assembly language into machine language. .Translate the above MARIE assembly language into high-level language "pseudo" code. Which control signals should contain a "1" for each steps in the JUMPI instruction? Draw the partial combinational logic of the hardwired control unit to handle the JUMPI (opcode C ) instruction. Print a copy of the second page of lecture 15 handout from: Explain why a microprogrammed control unit is slower than a hardwired control unit? Extend the partial microprogram below to include microoperations to decode and implement the execution of the instruction: ADD1 and JUMPI. (Fill in only bolded boxes)

Explanation / Answer

Dear user, Note: One question per one post regarding cramster rules.
           So, please provide one question at a time. 5) Microprogrammed control unit is slower than hardwaired control unit, because all instructions must go through an additional level of interpretation. But performance is not everything. Microprogramming is flexible, simple in design, and lends itself to very powerful instruction sets.If we use hardware control, the bit pattern in the machine instruction feeds directly into combinational logic within the control unit. In hardwired control, timing signals from the clock are ANDed using combinational logic circuits to raise and lower signals. In microprogrammed control, instruction microcode produces changes in the datapath signals. In hardwired control, timing signals from the clock are ANDed using combinational logic circuits to raise and lower signals. In microprogrammed control, instruction microcode produces changes in the datapath signals. The great advantage of microprogrammed control is that is the instruction set requires modification, only the microprogram needs to be updated to match: No changes to the hardware are required. Thus, microprogrammed control units are less costly to manufacture and maintain.
