Xilinx Enables Software Defined Radio to Accelerate the Deployment of Wireless Communication Standards

New DSP Solutions Include Algorithms for Forward Error Correction And Development Boards

SAN JOSE, Calif.
Jul 23, 2001

Xilinx, Inc. (NASDAQ: XLNX) today announced it has expanded its XtremeDSP™ initiative by unveiling a suite of new DSP intellectual property cores and third-party development tools for use in Xilinx Virtex®-II FPGAs. New solutions include forward error correction (FEC) algorithms and third-party development boards for software defined radio applications. Using these new tools, designers can now create software defined radios that are field upgradeable, allowing for cost-effective deployment of new wireless broadband standards such as W-CDMA, CDMA2000 and OFDM. A concept that once was considered futuristic, the deployment of software defined radio is now possible using high-performance Xilinx Platform FPGAs providing developers with a critical combination of extreme DSP performance and flexibility.

"FPGAs are ideal for implementing high-speed, parallel signal processing functions in a software defined radio," said Lee Pucker, system architect at Spectrum Signal Processing. "We frequently use the Xilinx Virtex family of FPGAs and accompanying IP products, which deliver optimal performance and flexibility."

The initial release includes seven ready-to-use LogiCORE™ algorithms for forward error correction (FEC) which are critical for detecting and correcting errors in wired and wireless communication systems during transmission of data to optimize the use of available bandwidth. The new algorithms include an enhanced Reed-Solomon Encoder/ Decoder, a Convolutional Encoder, a Viterbi Decoder, a Turbo Convolutional Code Encoder/Decoder, and an Interleaver/De-interleaver. These algorithms are significantly faster and smaller than other available programmable solutions for these same applications. Additionally, these cores may be used for communication applications such as broadcast equipment, wireless LAN, cable modems, xDSL, satellite communications, microwave networks and digital TV.

Several FEC cores are also available from third-party partners through the Xilinx AllianceCORE™ program, including a DVB-RCS Turbo Decoder from iCODING Technology Inc, a 3GPP Turbo Decoder from SysOnChip Inc., and a Reed-Solomon Decoder and 3GPP Turbo Encoder/Decoder from TILAB. Additionally, several Virtex-II FPGA based development boards for DSP and communications applications are also available from GV & Associates, Nallatech Limited, Alpha Data Parallel Systems Ltd., LSP, Spectrum Signal Processing, and HUNT Engineering. Information on these partners and third-party DSP products are available on the Xilinx web site http://www.xilinx.com/dsp.

"The addition of Virtex-II products to our HERON range have proved very popular with our customers, making some applications like software defined radio practical for the first time," said Pete Warnes, technical director of HUNT Engineering. "The growing availability of intellectual property cores for Xilinx devices makes it even more possible, or rather, it's now easier to join the dots."

The new FEC products expand the Xilinx XtremeDSP IP core offering to more than 70 products, allowing designers to integrate critical forward error correction algorithms, such as an array of turbo codes, in a single FPGA while supporting aggregate bandwidth demands of over 20 Mbps throughput. When used in conjunction with existing Xilinx DSP algorithms, development tools and the Virtex-II product family, these cores enable designers to develop sophisticated and flexible SDR platforms that can grow with the ever-changing wireless market requirements.

License Price and Availability

The cores are available immediately and downloadable over the web. The price for the Turbo Decoder and Encoder is $25,000 and $5,000 respectively. The Viterbi Decoder including the Convolutional Encoder is priced at $5,000, the Reed-Solomon Decoder and Encoder is $5,000 and $500 respectively, and the Interleaver/De-interleaver is $1,000. A 3GPP FEC bundle is available at $30,000 including the two Turbo cores, the Viterbi core, and the Convolutional Encoder. Prices on third-party products are available directly from the partners. Licensing information, instructions for downloading the cores, and partner contact information, as well as information on all other Xilinx IP products, can be found on the Xilinx IP Center, http://www.xilinx.com/ipcenter.
