Abstract :
The CMOS implementation of two high performance rotation processors using redundant CORDIC are reviewed and compared. One of the designs uses a variable scaling factor while the other is with constant scaling. The latter also incorporates some radix-4 CORDIC stages. Characteristics for 1.2 μm CMOS implementations are given
