FPGAs are overkill for single-chip replacement. There are quite a few non-Actel FPGAs that can automaticall configure themselves on powerup without an external microcontroller, usually from a serial or parallel flash chip connected to the FPGA. A subset of those include nonvolatile storage for the configuration in the FPGA itself, one example that I can think of is the Xilinx Spartan 3AN series. > For example, you'd probably need a few tuned op-amps to do the > integration of the SID filter. Why would you use external analog parts for that instead of filtering the signal in the digital domain? -ik Message was sent through the cbm-hackers mailing listReceived on 2012-02-27 22:00:05
