[tremor] tremor on 56k?

[William Brodie-Tyrrell]

Hi,

I'm implementing a home theater system using Motorola 56362 DSPs (120MHz).  
They're 24 bit not 32, so the MAC is 24x24->48 bits (56 bit accumulator).  
How difficult would it be to adapt tremor to this DSP?  If that can be done
then I'll be able to send ogg/vorbis streams directly to it over SPDIF.

I saw Nicolas Pitre's patch from October for things without 64bit mul, but
will there be other problems?  For example, the memory is 24 bits wide.  
Using 2/3 of twice as many words would be a lot sucky, if not infeasible.
