The Curtiss-Wright CHAMP-AV IV / SVME-416 is a quad-processor DSP board built around the QuadFlow architecture for high-performance signal processing in radar, sonar, and image processing systems. Four PowerPC MPC7447A/7448 processors operating up to 1.25 GHz deliver 40 GFLOPS peak computational power, each with dedicated DDR-250 SDRAM and AltiVec parallel processing capability. The non-blocking architecture achieves 3.2 GB/s on-board throughput and 2.0 GB/s instantaneous peak data transfer to memory, supporting simultaneous processor-to-memory, processor-to-processor, and I/O transfers with low latency.
