N2 - A two-dimensional inverse discrete cosine transform (2-D IDCT) processor comprises cosine angle index generators, pipelined multipliers and a symmetrical kernel. The 2-D IDCT processor of the invention has a five-stage pipelined structure for carrying out a coefficient-by-coefficient 2-D IDCT algorithm and can be operated at a clock rate of more than 50 MHz to achieve a pixel rate of about 400 MHz.
