You seem to mixing things up a bit. FPGA's are one sort of animal and
MPU "starter kits" are another sort. For FPGA's, look at the tools you
get with the kit. Basically, you have to translate your logic into
something that can be written into the FPGA and perform the desired
logic functions. I actually use Cupl for small FPLD's. MPU and MCU
starter kits allow small microprocessor applications to be tested. AVR
is an example of an MCU or MPU that is found in some starter kits. The
difference is really the difference between designing logic and
programming a computer. There is an Atmel FPGA that sports an AVR in it.
This is sort of a combination of the two and the kit has tools for both
the FPGA and the AVR. I haven't tried this one (no time - it is in a
cupboard) but I do use AVR. I have a deep dislike of Harvard
architecture but in the AVR ASIC I use, the Harvard architecture's most
glaring flaw is corrected.
The line between FPGA's and MCU's can be rather fine but you need to
decide whether you need "intelligent process", pure logic or a
combination and select the one kit that does the job for you. I have
used one of the AVR starter kits with an AT90S8515 AVR in it and found
it satisfactory for the very early stages of a development but the
AT90S8515 is not an FPGA but rather a flash based MCU.
