BittWare 6U cPCI Card Provides 8 TigerSHARC DSPs and Virtex-II FPGA

9/20/2002 - BittWare released the Tiger-6U-cPCI, a new DSP board featuring the industry's highest performance DSP - the 250 MHz TigerSHARC DSP (ADSP-TS101S) from Analog Devices. The 6U CompactPCI board boasts eight ADSP-TS101S DSPs, a 64-bit 66 MHz PCI interface via BittWare's Sharc®FINTM ASIC, up to 1024 MB of SDRAM, a Xilinx Virtex-II FPGA, and two PMC interfaces with I/O connections directly to the DSPs. With 12 GFLOPS of sustained processing power and over 5 Gigabytes/s of I/O bandwidth, the board's typical power consumption is only 20 Watts, yielding a power-to-performance ratio that is unrivaled. By adding two of BittWare's Tiger-PMC+ modules to the board, customers can bring the total DSP power up to 24 GFLOPS in a single 6U cPCI slot.

"Combining the agility and determinism of DSP with the speed and ease of use of RISC, the TigerSHARC is the most powerful real-time processor available today. Supporting up to 16 of these outstanding processors, the Tiger-6U-cPCI offers an amazing amount of processing power within a single slot," said Jeffry Milrod, President of BittWare. "The addition of the Virtex-II FPGA, combined with the plethora of high speed I/O options provides the flexibility of configuring the board for nearly any application, making the Tiger-6U-cPCI a tremendously powerful solution that rivals any board out there."

Tiger-6U-cPCI: Revolutionary Technology, Evolutionary Design
The Tiger-6U-cPCI's innovative board architecture is an evolution of BittWare's ten years of DSP board experience, combining the leading-edge technology of the ADSP-TS101S TigerSHARC DSPs with BittWare's SharcFIN ASIC technology, tightly integrated I/O, and rich set of software tools. With eight ADSP-TS101S DSPs at its core, the Tiger-PCI board offers up to 12 GFLOPS of processing power. The eight DSPs are arranged in two clusters of four. Each cluster is connected by a local bus, which also connects a 256 MB bank of SDRAM (one per cluster). The Tiger-6U-cPCI also features a third global bank of up to 512 MB SDRAM, which is shared between the two DSP clusters via local PCI bus. The local PCI bus is split in to three 64-bit, 66 MHz segments, providing over 1.5 Gbytes/sec of simultaneous data transfer.

A Xilinx Virtex-II reconfigurable FPGA is also shared between the two DSP clusters via PCI, allowing system designers to implement a wide range of additional functions such as complex digital interfaces, general purpose compute engines, or special purpose computing blocks. It provides 64 user I/O pins via the front panel and another 64 user I/O pins to the rear panel, all of which are configurable for single-ended or LVDS termination.

For other I/O interfaces, the board features eight 250 Mbyte/sec external link ports accessible via the rear panel, as well as an additional eight 250 Mbyte/sec link ports and two 64-bit, 66 MHz PCI interfaces to the PMC+ sites. The PMC+ sites are compatible with standard PMC modules or with BittWare's PMC+ I/O modules. BittWare PMC+ modules have access to the site's PMC+ extensions, which include four additional link ports connected directly to the DSPs.

Providing the backbone of the Tiger-PCI's architecture is BittWare's SharcFIN ASIC for the ADSP-TS101S (SFIN-101). The SharcFIN offers a comprehensive set of bus interfaces and peripherals for TigerSHARCs and provides a clean, elegant board-level implementation. It integrates a full 64-bit 66 MHz master PCI interface, a peripheral bus that interfaces the DSPs to peripherals such as Flash memory, and an extensive flag and interrupt multiplexer.

Available Software
Complete software support for the Tiger-6U-cPCI is available through BittWare's rich set of development and run-time tools. BittWare's DSP21k Toolkit allows users to easily develop application code and integrate the Tiger-PCI into their systems. Drivers are available for Windows and Linux; a source code porting kit is also available. The board is fully compatible with Analog Devices' VisualDSP++® code development tools and supports in-circuit emulation, and BittWare's VisualDSP Target provides a software debugger target that is integrated with VisualDSP++.

The board is also supported by SpeedDSP, BittWare's extensive set of highly optimized C-callable runtime libraries, and by SharcLAB, BittWare's target for MATLAB, Simulink®, Stateflow®, and Real-Time Workshop®. Real-time operating systems available for the Tiger-PCI include Analog Devices' VisualDSP Kernel (VDK), Wind River Systems' Virtuoso, and OSE Systems' OSEck.

Pricing and Availability
The Tiger-6U-cPCI is shipping now, with single piece pricing starting at $13,950. Other members of BittWare's Tiger board family include Quad PCI and PMC ADSP-TS101S boards.
