Quad-Core LEON4 Next Generation Microprocessor Evaluation Board

The GR-CPCI-LEON4-N2X evaluation board has been designed for evaluation of the Aeroflex Gaisler LEON4 Next Generation Microprocessor (NGMP) functional prototype device. The NGMP functional prototype is a system-on-chip with four 32-bit LEON4 SPARC V8 processor cores connected to a shared 256 KiB Level-2 cache and several high-speed interfaces, including an 8-port SpaceWire router and dual gigabit Ethernet interfaces. The architecture provides improved support for debugging and software partitioning together with extended support for both symmetric and asymmetric multiprocessing.

The board is a custom designed PCB in a 6U Compact PCI (CPCI) format, making the board suitable for stand-alone bench top development, or if required, to be mounted in a 6U CPCI Rack. The principle interfaces and functions are accessible on the front and back edges of the board, and secondary interfaces via headers on the board.
