—Year 2009 marks the completion of 50 years of the invention of CORDIC (COordinate Rotation DIgital Computer) by Jack E. Volder. The beauty of CORDIC lies in the fact that by simple shift-add operations, it can perform several computing tasks such as the calculation of trigonometric, hyperbolic and logarithmic functions, real and complex multiplications,(More)
—An efficient implementation of discrete cosine transform (DCT) computations are presented based on the so-called shifted discrete Fourier transform (SDFT), a generalization of the conventional DFT (DFT). Due to the simple form of the factorized matrices, the derived architecture can be easily constructed from the cascade of only two types of parameterized(More)
