is there a multi core FPGA board

??:confused:

you can instantiate numerous elements like processors (nios ii, arm, pic(?), cutom...)as many as you can fit[/B].

Since few years, we have seen FPGA in which the designer instantiate multiple Nios II processor which a good interconnect

see altera examples you can do this with any Altera Board, or any other board which implement FPGA, just take good examples.

I have never made multi-processor designs, but sure it is possible.

EDIT : Parallel VHDL Algorithm ??

VHDL is de facto parallel.

I suppose you mean parallel algorithm like multithread ?
