- Yes. The Xilinx XC???? (which is what I'll probably use)
- can be used as an SRAM, though I thought it might be better
- to use it as the controller and have a seperate SRAM -
- an XC3020 is well suited (at least space-wise)
- for the controller purpose -
- (the Data Book has a couple of pages devoted into creating
- a FIFO with the XC3020 chip)
- if you move up to XC4000 and above you will have plenty of room
- for some RAM, I think (not covered by my data book). And
- static RAM too! Since the University is moving up to the next
- generation of Xilinx chips (was it the XC5000??) I might be abble
- to pick up a few older chips cheaply. The only remaining problem will
- be the PCB board. -.
- Hm. Anyway, mail me on some more info on the PC 16650 -
- it might be worth considering, especially since XC3020/4000 chips
- are not THAT cheap.
