PowerStream 7000 Processor Module
The PowerStream® 7000 processor module is based on Freescale™ MPC7447A PowerPC® processors with AltiVecTM technology and the RapidIO® communications fabric, offering a performance density of 40 GFLOPS per 4U slot. Fitting more processing power into tight spaces enables full signal and image processing closer to the sensor in mobile platforms. Each of the five compute nodes (CN) on the processor module includes an MPC7447A processor, 1 GB DDR SDRAM, and 8 MB flash EEPROM, all connected to the RapidIO switch fabric by a Mercury RapidIO CN ASIC. The MPC7447A includes a 32 KB instruction and 32 KB data L1 cache, and an on-chip 512 KB L2 cache. The double data-rate SDRAM enables overlapping memory access requests from the local processor and remote accesses over the RapidIO switch fabric. The 8-MB flash EEPROM on each node is used for built-in test.
