MIPS ALU

Abstract

---

• Ainvert, Binvert, and Operation are inputs to a multiplexer. Operation is used to select among three operations: AND, OR, and Addition. Cin (carry-in) is used when we want to perform subtraction on the addition, as we are using 2’s complement representation

Features of ALU Control

MIPS ALU Control Signal

• Control Signal for MIPS ALU

Important

We generate ALUcontrol using opcode and funct with a truth table, then use a Karnaugh Map to simplify the table to create a concise logic circuit, as shown above.
