Any free/open source processor that can be programmed to a DE2 115 board

[varunme]

kindly someone suggest any free/open source processor that can be easily programmed to a DE2 115 board

I know about pentium microprocessor design on google try to search by yourself.

I don't know how much logic you have on that board, but look at the OpenRISC processor at Opencores, or the Mico8/Mico32 processors from Lattice.
Unlike the Altera Nios and Xilinx MicroBlaze, the Lattice Mico processors are free to use on any FPGA.

You must make the contact with the opencore maker, I thinks. Or you must to study by own(with authority form FPGA chip company in form of the data manuals).
Could you suggest the good lattice processor website for me ? Because I never heard this openproccessor, before.
