  1. Hi there,

    I'm thinking about implementing some data compression algorithms on an FPGA
    (Xilinx Virtex-II) using VHDL. Because speed and FPGA utilization are very
    important in this respect, I'd like to get some basic idea about complexity
    and achieveable speed before starting.

    Does anyone know about existing FPGA- implementations of

    - Run-Length-Encoding (RLE)

    - RLE with Burrows-Wheeler Transformation (BWT)

    - JBIG

    - Lempel-Ziv LZ77

    and the achieved throughput und device utilization? Maybe some details about
    existing ASIC implementations of the above mentioned methods may also

    Thanks in advance.

    Regards Gero
  2. thanks for the fast response, what about complexity, i.e. equivalent gate
