PCI real time video to disk
I have designed a PCI target with video capture. I
need to stream 12.5MB/sec to hard disk on a wintel PIII platform.
-move the data across the PCI bus from my PCI
device to PC main memory
-then make a BIOS call to save memory to
-should I just leave the memory on my target PC and
call the BIOS disk save command ?
What path does data take when going to the hard
disk (in a typical wintel PIII) ?
Does it originate from any memory
address either on a PCI device or mother board ?
Do the hard disk controllers connect directly to
the CPU bus or is the hard disk controller a PCI device ?
