huffmanProcessingUnit

#include "huffman_encoder.hpp"

void huffmanProcessingUnit (
    hls::stream <ap_uint <9>>& inStream,
    hls::stream <ap_uint <32>>& outStream,
    hls::stream <uint32_t>& inputSizeStream
    )

This module does updates lz77 byte data to 32bit data.

Parameters:

inStream	input packet of 8bit contains either literal or marker or match length or distance information.
outStream	output 32bit compressed data
inputSizeStream	input size of each block

    hls::stream <bool>& inEos,
    hls::stream <bool>& endOfBlock
    )

This module does updates lz77 byte data to 32bit data.

Parameters:

inStream	input packet of 8bit contains either literal or marker or match length or distance information.
