Alex mentioned configs of about 160K bytes, so that works out to about 1280kbits/50kbits or around 30 seconds of data transfer over JTAG, plus a few seconds to read the config file from a hard disk--sounds quite reasonable. It should be quicker than booting a PC. ;-)I suggest you may want to start reading xapp058 available on the Xilinx'web site - using a microcontroller to program FPGAs. In this case Apple can impersonate a microcontroller. Or you can start with some other implementation of this not quite trivial code that will need to be ported to Apple. Sounds like a fun project for somebody.
Alex, could you send me a sample configuration file? It would be very useful to give me an idea of the frequencies of the "ops" in the file. TIA, -michael NadaNet 3.0 for Apple II parallel computing!
