XMP-64 Development Board

The XMP-64 is available as an experimental board intended for research purposes only. Limited functional verification has been done and support for the XMP-64 is only available via the forum user community. The board is supplied on an as-is basis with basic tools support (including build and debug) and a simple example.

The XMP-64 is a prototype multi-processor board that demonstrates the scalability of the XS1 architecture. Based on the same board format as the XDK, the XMP-64 connects together 64 XCore processors in 16 XS1-G4 devices on a single PCB, delivering 25 GIPS.

IDC connectors provide access to IO's on the XCores in the same way they do on the XS1-G4 Development Kit, allowing external interfaces to be connected to the XMP-64. The board could, for example, be used to make an audio effects/synthesiser engine or to use it as an image processing/target tracking engine when connected to a camera.

The XMP-64 has a dual ethernet interface and is programmed over USB-2.
