fpga based multiprocessor

I want to design FPGA based multiprocesssor system. Is it feasible?

I think it depends on the processor core and the FPGA that you are going to use.

There are several FPGAs (XILINX & ALTERA) that have multi hard-cores cpus . One of the problems designing cpus on fpgas is the chains of development . That's why most fpga manufactures all have their own soft-cpu cores that can be configured to match your needs .

yes, it is feasible, why not?

for example on a 1Mgate Spartan3, you could have 5 microblaze processors and some peripherals. (5M spartan3 or a virtex-4/5/6 you could have even more)
the inter processor communication is what you have to figure out first. there are several options, for example multi-mastering on a (opb or plb or other) bus with a mailbox-RAM-OPB-peripheral, or something faster with dualport PLB FIFOs between each cpu-pair, shared memory interface...
