Transtech Introduces Octal TigerSHARC DSP VME Board with Xilinx FPGAs

4/21/2003 - Transtech DSP announces the TS-V39, an eight DSP VME format board using Analog Devices’ ADSP-TS101S (TigerSHARC® DSP). The TS-V39 features two clusters of four DSPs – each cluster with their own dedicated 128Mbytes banks of SDRAM and a local Xilinx Virtex-II FPGA to provide direct DSP data input/output and algorithm acceleration. With high performance processing and fast integrated I/O, the TS-V39 is well suited to software radio, radar, sonar and imaging applications.

The TigerSHARC DSPs at the heart of the TS-V39 are able to mix freely 1, 8, 16, 32 and 64-bit fixed-point as well as 32-bit floating-point data types natively on one device, enabling parallel operations, efficient data I/O and simplifying application development. Example benefits for telecommunications applications include being able to incorporate 8-bit data streams commonly used by Viterbi decoders, while using the increased precision of 32-bits for echo canceller algorithms and 16-bit data types to support equipment infrastructure; all on the same common platform. Four high-speed bi-directional link ports allow direct data transfer between TigerSHARC DSPs. Link ports provide a simple mechanism to smoothly scale the number of DSPs within the system without relying on bus-based structures.

The TS-V39 also includes either a Xilinx XC2V1000 or XC2V3000 Virtex-II FPGA that can also be used to provide a high-speed digital interface with a choice of I/O configurations. Since one of the key advantages of a DSP is its ability to move large amounts of data quickly, high-speed input/output ports are essential for efficient operation so as not to starve the DSP of data or cause it to wait unnecessarily. Direct FPGA driven I/O for each DSP cluster is provided by the TS-V39 through both the front panel and via the VME P0 backplane connections.

The modularity of the TS-V39 also permits a PMC site for data input/output via either the PCI backbone or directly into the FPGA data I/O port. To use this feature, one of the TigerSHARC DSP clusters has to be removed.

To enable fast development of optimal performance applications, TS-Lib-Float can also be provided. TS-Lib-Float is a hand-optimised signal and image processing library containing over 400 functions including FFTs, convolutions, correlation, filters, vector mathematics, linear algebra, matrix arithmetic, trigonometric operation and statistical functions. Software tools support is provided through GUI development tools such as Analog Devices’ VisualDSP++TM IDE, complete with C/C++ compiler, assembler, run-time DSP library, debugger and optimized libraries, JTAG emulators. Driver support is via VxWorks and LynxOS hosts.
