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.

  • Five compute nodes, each with:
    - MPC7447A processor
    - 1 GB DDR SDRAM
    - 8 MB flash EEPROM
    - Mercury RapidIO CN ASIC
  • Each CN ASIC has:
    - Enhanced DMA controller
    - High-performance memory system
    - Error checking and correcting
    - Metering logic
    - RapidIO interface
  • Performance density of 40 GFLOPS per 4U slot
  • Patented air-cooling system with ManagedAir™ technology
  • High processing density for mobile platforms
  • Drastically reduced latency
  • Increased processing throughput
  • Patented air-cooling system provides sufficient cooling to satisfy extreme performance density requirements

*As altitude increases, air density decreases and, therefore, the cooling effect of a particular number of CFM decreases. Different limits can be achieved by trading among altitude, temperature, performance, and airflow. Contact Mercury for more information.
