Course: Computer Architecture

Design a (very) simple CPU for an instruction set that contains only the following four instructions:

lw (load word), sw (store word), add, and jump (unconditional branch).

Assume that the instruction formats are similar to the MIPS architecture. If you assume a different format, state the instruction formats. Show all the components, all the links, and all the control signals in the datapath. You must show only the minimal hardware required to implement these four instructions. For each instruction show the steps involved and the values of the control signals for a single cycle implementation.
