TurboConcept's WiMAX Turbo Code IP Core for LatticeSC FPGA Devices

HILLSBORO, OR - NOVEMBER 27, 2006 - Lattice Semiconductor Corporation (NASDAQ: LSCC) today announced the availability of an IEEE 802.16 Convolutional Turbo Code (CTC) Decoder intellectual property (IP) core from TurboConcept, a new member of the ispLeverCORE™ Connection program. Through the program, Lattice and TurboConcept will provide complete system solutions for their mutual customers who are integrating system-level IP with the most advanced FPGA silicon architectures. The Lattice Connection program allows customers to easily access and integrate approved third-party IP products into Lattice programmable devices.

“Broadband wireless access is poised for exceptional growth, and FPGAs are a great fit for this growing market because their reprogrammability enables the instant design changes necessary to keep pace with evolving standards,” said Stan Kopec, Lattice corporate vice president of marketing. “To deliver maximum value, the FPGAs also must perform CTC decoding, which is why we are excited to join with our new IP partner, TurboConcept, as we continue our expansion into broadband wireless access. TurboConcept is an industry leader in Turbocode IP, and their expertise, coupled with our innovative LatticeSC™ FPGA architecture, will provide our customers a powerful design solution.”

“In a WiMAX system, the CTC decoder is one of the most demanding functions in terms of computational complexity, which makes it desirable to implement the decoder in an FPGA. Now that our widely used WiMAX CTC decoder is available on the LatticeSC FPGA devices, our customers can take advantage of both the Core’s benefits and Lattice’s innovative FPGA solutions,” said Jacky Tousch, TurboConcept’s co-founder and CTO.

IP Cores from TurboConcept

TurboConcept has ported, optimized and tested the TC1000 - WiMAX, an IEEE 802.16 CTC decoder IP core, on LatticeSC FPGA devices. This IP core supports all modes of the IEEE 802.16 CTC standard, including Orthogonal Frequency Division Multiplexing (OFDM) PHY and Orthogonal Frequency Division Multiple Access (OFDMA) PHY. Available in three speed versions, the typical throughput in a LatticeSC device can exceed 80 Mbits (at 5 iterations).

Pricing and Availability

The CTC decoder IP core is available now in netlist format for immediate purchase from TurboConcept. Customers should contact TurboConcept for pricing. TurboConcept also offers a variety of additional packaging and licensing options to suit specific customer needs.
