Instantiating and using ppc440 core in Virtex 5 FPGA

Question

I am new to Virtex 5 which has an embedded PPC440 core in it (XC5VFX70T). I am using the Xilinx ML507 board for my design.

I created the embedded core using XPS and instantiated it in my HDL project. As peripherals, I am using a DDR2 controller, BRAM, SRAM, one UART and a few GPIOs. However, I could not see any address/data bus ports from the embedded core which I can use in the FPGA fabric.

I have a few RTL IP cores which require memory mapping. How do I connect these IP cores to PPC440 core? Also there are a few registers implemented in the FPGA fabric which are used for system initialization. I want the PPC440 core to write to these registers during initialization. How can I achieve this if the embedded core doesn't have address/data bus as external ports?

Answer 1

Take a look at Xilinx UG200 and the MPLB interface. This looks like the port that you will need to connect your memory mapped peripherals to, probably with a decent amount of interface logic.
