Multilevel barrel shifter for CORDIC design
S.-J. Yih, Ming‐Yuan Cheng, W.‐S. Feng · Electronics Letters · 1996
The coordinate rotation digital computer (CORDIC) algorithm is used in numerous special purpose systems for real-time signal processing applications. It uses barrel shifters to complete shift operations. However, the barrel shifter occupies most of the area of the CORDIC chip. A new structure of multilevel barrel shifters is presented. With this structure the shifter size is reduced by 68%. The novel structure can also slightly reduce the latency time of shift operations.
