Theora video on the DM642 may not be entirely successful, but Vorbis audio is a different story. I’ve been experimenting with the Tremor integer-only implementation of Vorbis decoding.
Tremor offers two modes of operation. Normal mode, and low precision mode. Normal mode requires 64-bit intermediate results in arithmetic operations, whereas low precision mode only requires 32-bit [...]

Last year I did some experiments with the Theora video decoder on a Texas Instruments DM642 DSP. A royalty free video decoder is very attractive for embedded devices, but after some major restructuring for performance, some problems remained.
The main problem is that, unlike MPEG video, Theora video is not packed in the bitstream in the [...]
