Bit Serial Architecture for the Two-Dimensional DCT

  title={Bit Serial Architecture for the Two-Dimensional DCT},
  author={Manuel Parrilla S{\'a}nchez and Javier D. Bruguera and Emilio L. Zapata},
We present an architecture for the calculation of the Two Dimensional Discrete Cosine Transform and its Inverse that admits a high data rate. It is based on the row-column decomposition, the use of a fast algorithm, serial digit arithmetic and redundant coding. The critical path is set by the delay of a multiplexer plus a binary adder with as many digits as the width of the serial digits to be processed. We discuss its implementation for processing 8 bit 8x8 pixel blocks or 12 bit coefficients…
