RE[4]: Audio capabilities

LGB

Just a new thought here: I think, at least FIFO would be useful for one given purpose: using sole IRQ at the frequency of the playback rate is fine on a 50MHz CPU, right. However there is some problem if some would like to use DMA for whatever gfx trick for example (like fractional step to render "doom like corridor" or simply move memory areas etc) then DMA is "blocking" type on M65, so no CPU activity while DMA is working. Ergo, it's not possible to have playback during a DMA session as it blocks the execution of the CPU. However, if FIFO is "deep" enough, it can provide enough samples during a DMA transfer probably.
