With the rapid advancements in real time signal processing and digital signal processing, low power and high throughput circuitry plays a vital and challenging role for the designer. For a high performance digital signal processing system it is essential to have a MAC unit with gigantic speed and enormous throughput. The fundamental motivation of this work is to examine the full pipelined multiplier/ accumulator architecture and circuit design techniques which are suitable for achieving high throughput and with low power consumption. MAC unit comprises of multiplier, adder and accumulator/register. MAC based on the existing techniques has high delay due to accumulator without being affected by the large scale research and models. Henceforth, in this proposed framework we incorporated Carry Save Adder (CSA) technique considering various parametric constraints to assure the feasibility, efficiency and effectiveness in comparison with the existing methods. In a pipelined MAC unit, the delay estimation will assist in identifying the overall delay of the pipelined MAC unit. Many researches on the multiplier architectures including array, parallel and pipelined multipliers validates that pipelining is the most widely used technique to reduce the propagation delays of digital circuits. Therefore, the main motivation of this research is to investigate fully pipelined multiplier/accumulator architecture and circuit design technique which is suitable for implementing high throughput signal processing algorithms and at the same time achieve low power consumption.
