What is wrong with using a PC ? Use all 8 bits of the parallel port in DMA mode. The make an external circuit which will buffer and then serial clock the 8 bits out. If this is not quick enough, use more parallel ports. It is probably a good idea to use a real time OS, and not linux. Linux currently, is not best suited to low latency applications efficiently. Something like PLAN 9 might suit better.
It is probably overkill for something as simple as a D-Class amplifier, but it will be a good development system. If you write everything in C, it should be easily ported to an embedded system later.
