Subject: [oc] open lossless data compression core
Hi,
I have been trying to see if i can implement a lossless data
compression core (like gzip, etc) in HDL. I searched a lot for some
simple compression cores already in HDL that I could use. The only one
i found was the static huffman encoder/decoder in jpeg core from
opencores. That is not really usable for general data as its a static
encoder. I am interested in a general purpose data compression core.
Has anyone here ever written any kind of data compression cores in
HDL? From my study of the "deflate" algorithm, i think it will be
extremely tough to code it in verilog but, any other simpler
compressor implementation, that I can learn from?
I am surprised that no such simple cores exist. Is it very tough to
develop such a core?
Any opinion on this would be welcome. If by any luck, i get a large
number of replies, I also volunteer to edit and submit to OC as a
FAQ/HOWTO (depending on the results).
Thanks,
Abgoyal.
