Use instruction type to look up control signals in a table 2. Design FSM whose outputs are control signals • Either way, goal is same: turn instruction into control signals •In our datapath: lw •Goes through five structures in series: insn mem, register file (read), ALU, data mem

A single-cycle MIPS processor An instruction set architecture is an interface that defines the hardware operations which are available to software. Any instruction set can be implemented in many different ways. Over the next few weeks we'll see several possibilities. —In a basic single-cycle implementation all operations take the same 6 g. babic Presentation G 11 Datapath for LW and SW Instructions Control Unit sets: •ALU control = 0010 (add) for address calculation for both lw and sw •MemRead=0, MemWrite=1 and RegWrite=0 for sw •MemRead=1, MemWrite=0 and RegWrite=1 for lw 31 26 25 21 20 16 15 0 Project 2 - LC-2200-32 Processor Reference Manual This document describes the LC-2200-32 processor enhanced with interrupt support instructions, and the FSM for its implementation.
