RE: PC Vector generator card... (and ESB update)

Yep, I'm planning on talking to the IDMA port on the DSP just as a 16bit
port on the ISA card. (ie, not using any DMA on the PC side.) I
suppose there could be an interrupt on the ISA card to let it know when
the DSP is done drawing a frame, but that could just be a memory flag in
DSP RAM that the PC polls. (The IDMA port on the DSP is bidirectional.)

As always, you're more than welcome to do any PCI stuff! I'm really
jazzed to try this host memory access stuff, so over the next week or so
I'm going to try to cable up my evaluation board to the PC and see if I
can move data back and forth. My inexperience with even the basics of
DSP stuff is keep progress kinda slow at the moment though. (Although I
did manage to build and run some demos on the system over the weekend.
DSP's have all sorts of cool stuff... Circular buffers done in hardware,
zero clock reads and stores to CODECs... the mind boggles... ;-)
