New BittWare I/O Card Combines High-Speed A/D with Reconfigurable FPGA and Large Sample Buffer

7/31/2002 - BittWare, Inc. announced today the Barracuda-PMC+, a high-speed analog input card that provides data capture for two 14-bit, 105 MHz A/D channels and streams the digitized analog signals to a Virtex-II FPGA. Samples can then be buffered in a bank of up to 512 MB of SDRAM (256 Msamples), or streamed directly out via the SHARC link ports available on the PMC+ interface. In addition to providing A/D control and data distribution, the FPGA is also available for configurable preprocessing of the A/D data via a variety of third party IP cores, making the Barracuda-PMC+ a highly flexible solution for nearly any data acquisition application.

The 64-bit, 66 MHz PCI interface, coupled with the large sample buffer, addresses applications requiring generic high bandwidth and data buffering, while the SHARC link port interfaces offer tight integration options for low-latency applications. When coupled with one of BittWare's Tiger family base boards, the Barracuda-PMC+ can continuously stream out 420 MBytes/sec (210 MSamples/sec) via the PMC+ link ports, providing unprecedented output bandwidth.

"The Barracuda is an amazingly flexible I/O subsystem," said Jeffry Milrod, president of BittWare. "It offers unique functionality to the market; I'm excited that BittWare continues to push the technological envelope."

About the Barracuda-PMC+
The two 14-bit, 105 MHz analog input channels feed directly into the Xilinx Virtex-II FPGA, which features A/D interface software and two FIFOs. To interface the A/D data to the host, the Virtex-II contains a link port interface for directly accessing ADSP-TS101S or ADSP-2116x DSPs and a local bus interface to access the PCI host and the SDRAM buffer.

A BittWare SharcFIN ASIC provides a full 64/66 PCI interface and an SDRAM controller to interface the SDRAM and the Virtex-II to the PCI host. The SharcFIN interfaces to the PCI bus at 64 bits, 66 MHz for 528 MBytes/sec burst throughput and provides both bus mastering DMA capability and slave access to the Virtex-II and SDRAM.

The Barracuda-PMC+ is fully compatible with any PMC capable carrier board. When attached to one of BittWare's PMC+ capable carrier boards, it supports BittWare's PMC+ extensions, which include the four link ports directly to the Virtex-II FPGA.

IP Cores for the Barracuda
The Virtex-II is available for configurable preprocessing of high-speed A/D data, such as digital filtering, decimation, and digital down conversion. In addition to the plethora of standard cores available for the Virtex-II, BittWare has partnered with QinetiQ, Europe's largest science and technology research solutions provider, to provide an optional digital down converter (DDC) core for the Barracuda. QinetiQ can also provide DDC and other signal processing FPGA customization services.

Available Software Development Tools
BittWare offers complete software development tools that allow designers to easily develop application code and integrate the Barracuda-PMC+ into their systems. For user-configured pre-processing, XILINX also provides a complete suite of development tools for the Virtex-II. BittWare offers a Barracuda developer's kit for the Virtex-II that includes the VHDL source code for the A/D, link port, and local bus interfaces.

Pricing and Availability
The Barracuda-PMC+ is available now, priced at $1995 in OEM quantities.
