Quad ADSP-TS201 TigerSHARC DSP PCI-X Board

One cluster of four ADSP-TS201 DSPs @ up to 600 MHz

BittWare’s T2-PCI (T2PC) DSP board features the ADSP-TS201 TigerSHARC DSPprocessor from Analog Devices. This multiprocessor PCI-X board implements BittWare’s ATLANTiS (Advanced Transfer Link Architecture for New TigerSHARC) architecture to take full advantage of this high-performance DSP.

This architecture combines robust TigerSHARC processing with the versatile Virtex-II Pro FPGA from Xilinx to offer ultra high performance and unprecedented I/O bandwidth.

The board also provides a large on-board bank of SDRAM, flash memory for hostless boot, and a PMC site for adding additional processors or I/O capabilities.

The T2PC matches a cluster of four ADSP-TS201 TigerSHARCs with:

• High-bandwidth, low-latency off-board I/O, reconfigurable for nearly any application
• High-speed interprocessor communication network to facilitate scalability
• SharcFIN PCI-DSP bridge for integrating DSPs with PCI bus and other peripherals
• Comprehensive software for ease-of-use

High Performance TigerSHARC Processing

The T2PC features a cluster of four ADSP-TS201 TigerSHARC DSPs, which are interconnected by a 64-Bit, 100 MHz cluster bus. The ADSP-TS201 processor operates at up to 600 MHz, providing 3.6 GFLOPS of peak processing power.

Because of its superscalar architecture, the ADSP-TS201 is also efficient at fixed-point processing, with each DSP supporting 14.4 BOPS of processing. Along with 24 Mbits of on-chip RAM, each DSP also boasts four high-speed LVDS link ports running at up to 1 GB/sec each. Two link ports from each DSP create an interprocessor communications ring, and the remaining two link ports are routed to the on-board FPGA.Please follow the links below for details of BittWare development boards using both the first and second generation families of TigerSHARC® processors.

SharcFIN PCI Bridge & Host Interface

The T2PC features a BittWare SharcFIN PCI-DSP bridge chip that gives the DSPs low-overhead access to the host and PMC site via the 64-Bit, 66 MHz PCI interface.

The SharcFIN also provides a general purpose peripheral bus that allows the DSPs to access the Flash and the FPGA control registers. It also provides host access to the DSPs, on-board SDRAM, FLASH and FPGA control registers.

Low-Latency Off-Board I/O

The T2PC boasts a tremendous amount of I/O bandwidth and options, including eight LVDS link ports, a PMC site with BittWare’s PMC+ I/O extensions, high-performance digital I/O headers,and eight RocketIO high-speed serial transceivers. Total potential I/O bandwidth is greater than 6 GB/sec.

Xilinx Virtex-II Pro FPGA

A Xilinx Virtex-II Pro (XC2VP20) FPGA adds tremendous flexibility to the board and is useful for routing communications, translating protocols, and implementing algorithms. It is used to implement eight on-board TigerSHARC link ports and supports a variety of external digital I/O (DIO), flags, and interrupts. The Virtex-II Pro’s eight RocketIO high-speed serial transceivers, which are brought off-board, provide additional external communications.

ATLANTiS: A Superior Architecture for a Superior Processor

To facilitate off-board I/O and provide communications routing and processing, the T2PC features BittWare’s ATLANTiS architecture, which is implemented in the Xilinx Virtex-II Pro FPGA. All off-board I/O for the board, which includes external link ports and digital I/O blocks, is routed through the FPGA, which can support a throughput of 4 GB/sec. By tightly integrating the DSPs, PCI bridge, PMC interface, and I/O peripherals with the on-board FPGA, ATLANTiS gives designers nearly infinite options for configuring and routing the I/O.

TigerSHARC Link Ports

The eight bi-directional TigerSHARC link ports routed to the ATLANTiS FPGA provide 4 GB/sec of data transfer between the DSP cluster and the FPGA. Using its eight RocketIO high-speed serial transceiver channels and its digital I/O blocks, the FPGA can communicate off-board at greater than 4.8 GB/sec. It can be configured to connect the I/Os to each other or to the ADSP-TS201 link ports, allowing any combination of inputs and outputs to be routed together.

Development Tools

BittWare offers complete software development tools that allow designers to easily develop application code and integrate the BittWare TigerSHARC-PCI-X card into their systems.

BittWare's BittWorks DSP21k Toolkit allows users to easily develop application code and simply comunicate with all of BittWare's ADSP-TS201 DSP cards. The board is fully compatible with Analog Devices' VisualDSP++® and supports in-circuit emulation. It is also supported by TS-Lib, BittWare's highly-optimized, C-callable runtime libraries, and by SDL's DSPdeveloper, target for MathWorks MATLAB, Simulink® and Real-Time Workshop®.
