The CHAMP-AV4 is the third generation of quad NXP (formerly Freescale) Power Architecture DSP board with the QuadFlow architecture providing high bandwidth connections between four 7447A/7448 processors. Each processor, capable of up to 10 GFLOPs peak, is equipped with its own bank of DDR SDRAM with 2GB/sec peak bandwidth. Processors are interconnected via 100MHz PCI-X busses. Utilizing the QuadFlow ability to handle up to four simultaneous transfers, the AV IV can deliver up to 3.2GB/sec of on-card inter-processor bandwidth.
