Design and Implementation of High Performance MAC Unit

A design of high performance 64 bit Multiplier-andAccumulator (MAC) is implemented in this paper. MAC unit performs important operation in many of the digital signal processing (DSP) applications. The multiplier is designed using modified Wallace multiplier and the adder is done with carry save adder. The total design is coded with Synthesize and simulate by verilog-HDL.
