The CHAMP-AV4 is the third generation of quad PowerPC 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.
