4M Wireless Completes LTE Protocol Stack Software Port for Tensilica's 3GPP LTE Reference Architecture

SANTA CLARA, CA and LONDON--(Marketwire - October 6, 2010) -  Tensilica,® Inc. and 4M Wireless today announced that 4M Wireless has completed its port of the PS100 LTE protocol stack to Tensilica's ConnX™ Atlas LTE reference architecture and has also officially joined Tensilica's Xtensions™ partner network. 4M Wireless has also ported its PS100 LTE protocol stack to the LTE system platform from Blue Wonder Communications, another Tensilica partner.

The 4M Wireless PS100 LTE protocol stack is a 3GPP Release 8 compliant implementation of the LTE protocol stack for User Equipment (UE) terminals. It consists of a fully optimized Layer 2, Layer 3, and NAS LTE protocol software enabling the highest uplink and downlink data rates. It is optimized for low power consumption and efficient processor utilization.

Tensilica's Atlas LTE reference architecture implements the complete 3GPP LTE Layer 1 PHY at CAT4 data rates in an efficient programmable solution based on its customizable Dataplane Processor (DPU) and ConnX DSP (digital signal processors) IP cores. The Atlas reference architecture consists of highly optimized application-specific ConnX DSPs and DPUs, tailored to meet the low-power requirements and high-computing power requirements of 4G mobile wireless handsets and base stations.

"The 4M Wireless highly qualified team quickly and efficiently ported its software to our platform," stated Eric Dewannain, Tensilica's vice president and general manager, baseband business unit. "Now together we can offer customers a total solution for fast implementation of new LTE equipment."

"The Tensilica Atlas reference architecture provides a total solution for LTE UE design," stated Atif Malik, CEO, 4M Wireless. "4M Wireless already works with a number of customers and partners that use the Tensilica architecture, thus the two companies provide a proven solution to the market. By using a series of optimized processors, Tensilica gets maximum efficiency while keeping the power budget as low as possible."
