6U VME — Power PC 7448ST SBC

Applications such as signal intelligence and automated testing equipment (ATE) require an embedded computing platform that is capable of collecting, analyzing, and disseminating large amounts of data in real-time. Cornet Technology’s Celero CVME-7448ST solution is ideal for systems designers choosing commercial-off-the-shelf (COTS) products to achieve substantial cost savings and a reduced time-to-market.

Within a VME 6U form factor, the Celero CVME-7448ST hardware uses a Freescale PowerPC MPC7448 processor running at 1.2 GHz. Each processor has an AltiVec™ vector-processing engine that is capable of optimizing the performance of mathematically intensive operations. The processor node has a 1 MB on-chip L2 Cache, 512 MB or 1 GB DDR2 SDRAM, and 256 MB FLASH. The board has two configurable multi-protocol (RS-232/422) serial ports; two USB 2.0 ports; and two 10/100/1000Base-T Gigabit Ethernet ports, all selectable for front or back access; and two PMC sites for hosting data acquisition or signal conditioning modules or peripherals such as video, MIL-STD-1553B or storage. 

Featuring the Tundra Tsi109 host-bridge controller, the Celero CVME-7448ST hardware offers much higher performance per watt than comparable products in the market – a key consideration of military embedded applications with tight power budgets, and improved signal integrity providing significant improvement over older generations of VME PowerPC single board computers. By incorporating the latest DDR2 technology and the Tundra controller into the design, memory latency caused by pipeline blockage is eliminated improving performance by up to 9% and overall power consumption is reduced by up to 6W over boards using older technology.

The Celero solution includes board support packages (BSPs) for VxWorks and Linux operating systems. This lets systems designers seamlessly integrate their application code into a real-time operating system or open-source environment. Software developers can conveniently use the on-board JTAG interface, status LEDs, front panel reset toggle switch, and power-on built-in test features for rapid development.
