Fast algorithms for N-point shifted discrete Fourier transform (SDFT) are proposed by efficient matrix factorization¡DThe resulted matrix decomposition is realized by a cascade of several basic computation blocks with each block implemented by a parameterized IP module¡DBy combining these modules with different parameters, it is easy to implement a wide variety of digital transforms, such as DCT/IDCT in image/video coding, and modified DCT (MDCT) in audio coding¡D The transform processors realized using the parameterized IP modules have advantages of locality¡Amodularity¡Aregularity¡Alow-cost¡Aand high-throughput¡D Furthermore ¡Athe computation accuracy can be easily controlled by selecting different numbers of IP modules with proper parameters in the processors.
