Just wanted to make sure of some things..

I guess you haven't done the math ... I don't think linux will be your primary constraint ;-)

Don't be surprised. You're mixing apples and oranges here. Linux is not an "FPGA program" ... it's not

a digital circuit ... it's software ... a collection of opcodes and associated data that are executed by a

stored program computer ... in this case the Nios CPU. You can have as many "FPGA programs" as you

can fit on your FPGA. If one or more of them happen to be a Nios CPU, you can "run" linux on the

Nios CPU(s).
