216DB61 HESG324063R0100 HESG216882A combines dynamic performance, compactness, and ease of use to accelerate system development on Pentek’s high-performance VME boards. On-board Signal Processing: With a density equivalent to more than 11 million system gates, the Xilinx XC2VP100 Virtex-II Pro FPGA provides a powerful signal processing resource for large data streams from A/D converters. The on-board logic first demultiplexes the 2 GHz raw 10-bit A/D samples eight times to produce 80-bit words at a reduced rate of 250 MHz for successful transfer to the FPGA.The FPGA then performs a variety of standard functions on the data, including memory transfer, formatting, triggering, gating, and transfer to the FPDP and VMEbus interfaces.

216DB61 HESG324063R0100 HESG216882A Large amount of memory to support transient capture and buffering: the Model 6826 also has extensive memory resources. Dual 64-bit high-speed DDR SDRAM provides a total of 512 MB or 1 GB of memory for storing raw data in transient capture mode. This memory can also be used as a resilient buffer to store burst signals, such as radar pulses, in real time and then transfer them to the I/O interfaces at a low continuous rate. Custom FPGA configurations can utilize this large memory for more complex applications. 16 MB of flash memory allows the boot code for two IBM 405 PowerPC microcontroller cores to be stored within the FPGA.
