This is a resource optimized version of huffman treegen kernel. It takes literal and distance frequency data as input through single input stream and generates dynamic huffman codes and bit length data which is output through a single output stream. This kernel does not use DDR in any way and is optimised for both speed and low resource usage.
Parameters:
freqStream | 24-bit input stream for getting frequency data |
codeStream | 20-bit output stream sending huffman codes and bit-lengths data |
