Multiprocessor Accelerator

The Excalibur 333 is the latest addition to the family of multiprocessor accelerators. Each includes four PowerPC 640e microprocessors. One configured on a 6U VME motherboard delivers 2.66 GFLOPS of performance. Four daughter cards on a 9U VME motherboard deliver 10.66 GFLOPS, with total performance in a single VME chassis of 170 GFLOPS.

The accelerator uses a version of the 333 MHz PowerPC 604e microprocessor to achieve a maximum multiprocessor computing power in a single VME slot. Coupled with SKY's advanced memory system design, the PowerPC 604e microprocessor sustains memory bandwidth at 667 MB/s, and executes a 1 K complex FFT in 174 µs. This combination makes it ideal for image and signal processing applications such as radar, sonar, medical imaging, and imaging analysis.
