This is the core compression module which seperates the input stream into two output streams, one literal stream and other offset stream, then lz4 encoding is done.


PARALLEL_UNITS number of parallel units
MAX_LIT_COUNT encoded literal length count
inStream Input data stream
outStream Output data stream
max_lit_limit Size for compressed stream
input_size Size of input data
endOfStream Stream indicating that all data is processed or not
compressdSizeStream Gives the compressed size for each 64K block
index index value
