WebDatapath and Control . Datapath: Memory, registers, adders, ALU, and communication buses. Each step (fetch, decode, execute, save result) requires communication (data transfer) paths between memory, registers and ALU. Control: Datapath for each step is set up by control signals that set up dataflow directions on communication buses and WebData paths for MIPS instructions.
