Datapath for Single Cycle Implementation: PreLab

A resonable way to start a datapath design is to examine the major components required to execute each class of MIPS instruction. When we show the datapath elements, we will also show their control signals.

To execute any instructions, we must start by fetching the instruction from memory. To prepare for executing the next instruction, we must also increment the program counter so that it points at the next instructions, 4 bytes later.
