Description
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.
Main Features:
- 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.
