Dolby Digital AC-3 Decode on an FPGA - Possible ? Big ?

Sep 28, 2005 2 Replies

I'd like to hear from anyone who has experience or knows of any FPGA based implementations of Dolby Digital AC-3 decode (or similar algorithms) on an FPGA.



Specifically, I'd like to find out how resource intensive this may be. Any comments would be appreciated.

I believe the processing power requirements of AC-3 decoding are similar to multi channel mp3 decoding. In that case a microblaze processor with some extra hardware for DCT and Huffmann should be sufficient.

Of course you can also do a full hardware implementation, but for the software one you can port some open source software decoder.

And if you do port the open source decoder, libac3/liba52, be sure to heed the (GPL) license.

ps. would anyone be interested in an RTL AC3 decoder on commercial terms? I could probably crank one out in a few months part time.
