XILINX ENABLES FLEXIBLE AND LOW COST FORWARD ERROR CORRECTION
SOLUTIONS WITH IP CORES OPTIMIZED FOR SPARTAN-IIE FPGAS
FEC solution ideal alternative for application specific standard
SAN JOSE, Calif., April 10, 2002 - Xilinx, Inc.
(NASDAQ: XLNX), announced today the immediate availability of
parameterizable forward error correction (FEC) LogiCORE products
for use with its Spartan-IIETM FPGAs. The cores include a Reed-Solomon
Encoder and Decoder, a Convolutional Encoder, two Viterbi Decoders,
and an Interleaver/De-interleaver. When implemented in a low cost
Spartan-IIE FPGA, the cores provide system architects and digital
signal processing (DSP) designers with the ability to quickly
build cost effective and flexible solutions.
"Designers no longer need to concern themselves with being
locked into a fixed FEC device that may become obsolete,"
said Per Holmberg, senior product marketing manager for IP Solutions
at Xilinx. "The flexibility of these parameterizable cores,
along with the cost-effective Spartan-IIE series, really changes
the dynamics of system design, making it a preferred alternative
to application specific standard products (ASSPs)."
In addition to providing a competitively priced solution, the
combination of the Spartan-IIE series with the FEC cores offers
key benefits when compared to fixed function ASSP solutions. Designers
can achieve tremendous flexibility both through the parameterization
capability of the cores and through the programmability of the
Spartan-IIE devices, allowing changes in specification late in
the design cycle. Additionally, using Spartan-IIE FPGAs, designers
can "future-proof" their designs. These low cost FPGAs
support field upgradability, enabling their end products to be
updated remotely. The combined solution of FEC cores and Spartan-IIE
FPGAs allows designers to customize their products to meet their
exact requirements, rather than being forced to pay for a fixed
function alternative with unnecessary components.
The newly released FEC cores include features that make them ideally
suited for use with Spartan-IIE FPGAs. The IEEE 802-Compatible
Viterbi Decoder includes best state initialization, resulting
in improved performance with bursty data. The General Purpose
Viterbi Decoder is available as a parameterizable netlist with
a bit-error-rate (BER) option to monitor the error rate on the
transmission channel. It also has both a serial and parallel architecture
allowing the designer to prioritize area or speed for his design.
A Convolutional Encoder is also available to support the transmit
end of the link. The FEC offering also includes a high speed,
very compact Reed-Solomon Encoder and Decoder and a Convolutional
and Rectangular Block Interleaver/De-interleaver.
License price and availability
The LogiCORE products are available immediately under the terms
of the SignOnce IP License and downloadable over the web at www.xilinx.com/dsp.
The IEEE 802-Compatible Viterbi Decoder core is sold as both parameterizable
source code and as a fixed netlist for $25,000 and $7,500 respectively.
The General Purpose Viterbi Decoder is sold as a parameterizable
netlist for $5,000. All Viterbi solutions include the Convolutional
Encoder for no additional charge. The Reed-Solomon Decoder and
Encoder are $5,000 and $500 respectively, and the Interleaver/De-interleaver
is $1,000. In addition to support for the Spartan-IIE family,
these cores also support Xilinx VirtexTM family of FPGAs using
the latest ISE 4.2i version of the Xilinx design software. For
