New 2D systolic array algorithm for DCT/DST
M.H. Lee, Y. Yasuda · Electronics Letters · 1989
We present an algorithm and the architecture of a 2D systolic array processor for the DCT (discrete cosine transform) and the DST (discrete sine transform). It is based on the IDFT (inverse discrete Fourier transform) version of the Goertzel algorithm via Homer's rule. This 2D systolic array for the DCT/DST can be met by achieving a systematic technique for transforming algorithms to specific forms for mapping onto 2D systolic arrays.
