Design of High Accuracy Fixed Width Modified Booth Multiplier for MAC Unit

In the majority of Digital Signal Processing (DSP) applications the critical operations are the multiplication and accumulation. Real-time signal processing requires high accuracy and high throughput Multiplier-Accumulator unit (MAC) to achieve a high performance digital signal processing system. We successfully proposed the MAC unit using high accuracy fixed-width Booth multiplier. The carry is generated from LSB minor part using Bitonic sorter based Carry generator. A sorting network is a special kind of sorting algorithm, where the sequence of comparisons is not data-dependent. Sorting network suitable for implementation in hardware or in parallel processor arrays. Bitonic sort is developed on the basis of the 0-1 principle. The 0-1-principle states that a comparator network that sorts every sequence of 0's and 1's in a sorting network. The simulation results show that the performance is superior to that using the direct-truncation fixed-width Booth multiplier.
