详细描述：DCT soft core is the unit to perform the Discrete Cosine Transform (DCT). It performs twodimensional 8 by 8 point DCT for the period of 64 clock cycles in pipelined mode.

特色： more than 300 MHz sampling frequency, 64-cycle calculation period,

  approximately 330 CLBs and 4 DSP48E in Virtex-5 device,

  2 DSP48E when the scaled output data mode is used,

  8-bit input data,

  11-bit coefficients,

  12 – bit results,

  pipelined mode,

  latent delay from input to output is 132 clock cycles,

  structure optimized for Xilinx Virtex, Spartan FPGA devices.
