Eight Sharcs ride the VME
Providing developers with a peak 960 MFLOPs, the DBV68 DSP VME board boasts eight ADSP-2106x Sharc processors. Designed for medical imaging and sonar applications that require fast data-transfer rates between peripherals, the board can either be used stand-alone or in an array with other DSP boards. Communication to other boards is provided using any of 16 link ports that provide 40-Mbyte/s data-transfer rates. The eight Sharcs, running at 40 MHz, are arranged in two clusters of four processors. This architecture gives each Sharc processor shared access to both optional DRAM and SRAM and the internal SRAM of other processors. Software support is provided in the IXZ multiprocessor development toolkit that provides C-callable libraries for mail queueing, semaphores, and interrupts.
