status

• compress bytedone+valid_out+laststate to bitstream（evaluate the best bits） can't!
  
• minimize data width of nb_bits done!
  
• create another example of 256 symbols working...
  

progress

sync the decoder nbBits width with encoder nbBits width done
parameterization count of symbols
can't improve last state due to BUFF design

quickly compare my implement with htANS of paper

summary

• Naj's implement is tANS codec in 2015
• 2017 and 2019 is a pure decoder of FSE
• he compare with a table HUFFMAN

pros of my implement

coder

cons of my implement

gen tables module is software

future work

• create another example of 256 symbols
• implement gen tables module by hardware
• learn Naj's 3-level pipeline
