Pls Help!! Using DE2 board to implement multicore(can't fit design)

Hi All

I am trying to put the Altera Design Example (Nios II Multiprocessor Design Example)

http://www.altera.com/support/examples/nios2/exm-multi-nios2-hardware.html

to the DE2 board.

But after I cut from 5 slaves to even 2 slaves, it still cannot compile successfully.

Error 170048 Selected device has 105 RAM locations of type M4K. However, the current design needs more than 105 to successfully fit.

Ps the device for DE2 board is Cyclone II EP2C35F672C6

I am a beginner of FPGA, pls help!!

In the attachment is the design file.

Thanks
