Dear all
I search for a good resource to design a RISC processor as an application to complete my study for VHDL. I need a source to help my how to implement the RISC topics as pip line, ..etc ito real H/W

thanks

personally, I think the openrisc documentation and scripts (if there is any) are less user friendly compared to leon2, especially for entry level user.

Hi, all
Can someone can provide a entire design ,that means .v code and synthesis scripts ,sta scripts, formal verification scripts, p&r scripts .etc.
I think these shall be very useful than only code.

The DLX processor has a normal 5-stage pipeline. No need for stalls for load and store operations.

It has a clean structure, no twists and turns, and is described in one of the Patterson-Hennessy books. This is a good starting point.

Also it should be easy to get, VHDL/Verilog code for some DLX/MIPS R2000 adaptation.

Leon and openRISC are more mature.
They have simulation environment for debug and uClinux operation
system.

Your code is verified by silicon?
Which architecture is it compatible?
