Looking for FPGAs with processor

Altera has performace information about NIOSII including how it compares to chips and any FPGA competition. I don't see that information on the Altera web site. You would likely have to get it from the local Altera sales force. You also may be able to get a loaner NIOSII development kit from Altera's university program. I'm not sure if I should spend Altera forum time to point you to their competition, but it is called micro-blaze.
