A 0.75-V 58-MHz 340-μW SOTB-65nm 32-point DCT Implementation Based on Fixed-rotation Adaptive CORDIC

In this paper, a Silicon On Thin Buried-oxide (SOTB) implementation of a 32-point Discrete Cosine Transform (DCT) is presented. The architecture is based on the fixed-rotation adaptive COordinate Rotation DIgital Computer (CORDIC) algorithm.
