SySDSoft Ports Complete LTE Protocol Stack to Tensilica's Atlas LTE Reference Architecture

(July 28, 2010)

SANTA CLARA, CA -- (Marketwire) -- 07/28/10 -- Tensilica,® Inc. and SySDSoft announced today their partnership to port SySDSoft's LTE UE protocol stacks onto Tensilica's ConnX™ Atlas LTE (long-term evolution) reference architecture for User Equipment (UE). SySDSoft has joined Tensilica's Xtensions™ partner network. SySDSoft has also ported its LTE protocol stack to the LTE system platform from mimoOn, who also is a Tensilica partner.

SySDSoft's LTE Protocol Stack for UE combines highest-to-date data rates (290Mbps DL and 75Mbps UL simultaneous throughput) with a small footprint required in today's mobile platforms. SySDSoft has designed its LTE protocol stack leveraging its extensive experience in a myriad of wireless standards including WiMAX-2005 and CDMA-DO. The solution comprises Layer 2, Layer 3 and NAS following the 3GPP September Release. The Layer 2 solution comprises the MAC, RLC, and PDCP with optimized code for the time-critical ROHC, support for HW ciphering/deciphering, ARQ, and channel prioritization. The RRC (Layer 3) implementation supports the cell selection, mobility, paging, and connection establishment and release.

Tensilica's Atlas UE LTE reference architecture implements the complete 3GPP LTE Layer 1 PHY at CAT4 data rates based on its customizable and programmable Xtensa™ Dataplane Processors (DPUs) and ConnX DSP (digital signal processor) IP (intellectual property) cores. Tensilica is unique among IP suppliers as its Xtensa DPUs scale from very small micro cores to powerful 3-way VLIW DSPs ideal for power-efficient execution of Layer 2 and Layer 3 protocol stacks such as the solution from SySDSoft.

The Atlas UE LTE reference architecture is uniquely capable of meeting the low-power consumption and high-computation requirements of both the Layer 1 PHY and Layer 2/3 and NAS protocol levels of 4G mobile wireless handsets and base stations.


"SySDSoft's LTE UE protocol stack is a proven, efficient software solution and a natural complement to our Atlas reference architecture," stated Eric Dewannain, Tensilica's vice president and general manager of the wireless baseband business unit. "By working together, we can offer our customers a total hardware and software solution ranging from Layer 1 to Layer 3 for new LTE equipment."

"Tensilica's Atlas LTE UE reference architecture is a complete and efficient programmable multi-core solution for the hardware and Layer 1 software, which has been selected by several customers we encounter in the LTE UE market," stated Khaled Ismail, CEO, SySDSoft. "Our Layer 2, Layer3 and NAS software is a natural fit and will help speed new design efforts."
