Multiplexer 9bit

Understanding the Multiplexer in a 9-bit ALU: Selecting Operations

Key Role in an ALU

In a 9-bit Arithmetic Logic Unit (ALU), a part called the multiplexer, or simply "mux," plays a crucial role. It's like a switch that decides which math operation the ALU should perform.

Choosing Between Four Operations:

• The multiplexer uses a signal called select to choose between four options (like adding or subtracting).

• Depending on this signal, it picks either inputA or inputB.
