| That makes sense with the hardware at hand. With the Lexicon PCM70/480L and earlier hardware it makes sense to treat the memory as a big shift register as you don't really have any other option.
I'm just starting to work on the host-DSP interface. I've started to figure out how I should be setting up the DMA channels to support that, and I'm using an interrupt line from the host to the DSP signalling the start of a transmission. Hopefully I'll try that tomorrow. |
