In computing, especially digital signal processing, the multiply–accumulate (MAC) or multiply-add (MAD) operation is a common step that computes the product of two numbers and adds that product to an accumulator. The hardware unit that performs the operation is known as a multiplier–accumulator (MAC unit); the operation itself is also often called a MAC or a MAD operation. The MAC operation modifies an accumulator a: WebBinary Single Precision Floating-point Fused Multiply-Add Unit Design (Verilog HDL) -- input operands A,B, C --> result: A*B+C -- for subtraction, flip the sign bit of C operand …
