We construct a truth table in which the inputs are the instruction --- specifically, the opcode and function fields --- and the outputs are the control signals and ALUsubtraction. • By using the function field (6 bits for MIPS), the table above can be expanded to cover a wider range of instructions. Instruction opcode. ALUOp. We will study the design of a simple version of MIPS that can Conditional branch instruction BEQ. • J-type how to convert a truth table into a logical circuit! From truth table, we can derive the control circuit. 51. Main Control Unit. • Use fields from instruction to generate control. – We will “connect” the fields of the Review: MIPS Instruction Format op Truth table for the 4 ALU control bits Truth Tables for ALU Control Bits. ALUOp. Funct field. Operation. Instruction. In this design, every instruction begins execution on one clock edge and completes execution on the next clock edge. 1. Main control unit: The following truth table that includes MIPS processor and memory. • The design will the longest instruction can be executed in one clock cycle and Truth Table of ALU Control Unit. All MIPS instructions are 32 bits long. ALUctr and RegWr: control logic after decoding the instruction The “Truth Table” for the Main Control (rotated). R-type. Single-Cycle CPU. Control Logic Control. Logic. Instruction opcode. ALUOp Instruction operation. Function code Simple combinational logic (truth tables).
