Implementing a Mali 400MP in the Versatile Express

Dear all,

I will soon receive a Versatile Express platform with the Cortex A15x2, version [color=#222222][font=arial, sans-serif][size=2]V2P-CA15_A7 (big.LITTLE) for testing and benchmarking purposes. From what I've heard and seen though, due to the lack of a GPU all UI rendering must be done by the CPU, causing a huge performance drain.[/size][/font][/color]
[color=#222222][font=arial, sans-serif][size=2]I would like to implement a Mali400 on the board (FPGA?), but I don't know how that's done. [/size][/font][/color]
[color=#222222][font=arial, sans-serif][size=2]Could someone perhaps give me a few hints?[/size][/font][/color]

[color=#222222][font=arial, sans-serif][size=2]Thanks in advance,[/size][/font][/color]

    I just found something. It says here that the Motherboard Express has PCIe slots and "PCIe x8 Link Root Complex* or endpoint supported"
    "* Features stated here will depend on the daughterboard used."

    I know that the A15x2 doesn't suppport the endpoint nor the Root Complex so that would have to be embedded on an FPGA board.
    With some basic drivers for, say, the GT520 PCIe x1 I could use some relatively high end graphics for both benchmarking and UI rendering purposes. Besides, I've always wondered what it would be like to use a desktop GPU with Android. (not the 'Desktop class GPU' stuff Nvidia promotes, the Tegra3 GPU isn't that great and it gets beaten easily by the Mali400 @ 400 MHz from the SGS3.)
