Tensilica's ConnX D2 DSP Engine Wins EDN Top 100 Electronic Products Award for 2009

Picked as One of the Top Innovations of 2009 (December 21, 2009)

SANTA CLARA, CA -- (Marketwire) -- 12/21/09 -- Tensilica® Inc. today announced that its ConnX D2 DSP (digital signal processing) engine won a coveted place on the EDN Magazine Top 100 Electronic Products of 2009 list, published at The small, low-power ConnX D2 DSP engine was one of four products picked as the best DSP products of the year by the editors of EDN Magazine.

The ConnX D2 DSP engine provides uncompromised performance from C code, unlike many other DSPs that require time consuming assembly coding for maximum performance. This means that virtually any C program, including those written with C intrinsic functions for the TI C6x family or ITU (International Telecommunications Union) reference code, can run unmodified and with excellent performance on the ConnX D2 DSP engine.

With the large ITU software code base available, the ConnX D2 DSP engine is ideal for telecom infrastructure and VoIP (Voice over Internet Protocol) applications. With its small size (less than 70,000 gates), the customizable ConnX D2 DSP engine is also ideal for a wide variety of low-power portable consumer applications including mobile wireless devices, next-generation disk drives and data storage, home entertainment devices, and computer peripherals.

"We are honored that the editors of EDN Magazine recognized the important innovations in our ConnX D2 DSP engine," stated Steve Roddy, Tensilica's vice president of marketing and business development. "Our customizable dataplane processors have long been used as DSPs in many applications, including our market-leading 24-bit HiFi audio engine DSPs. Now, with the ConnX D2 DSP engine joining the other members of the ConnX DSP family, we have communications DSPs at all major performance points, all with the full benefit of our extensive optimizing compiler technology."

The ConnX D2 DSP engine option adds dual 16-bit MAC units and an 8-entry, 40-bit register file to the base architecture of the Xtensa LX DPU (dataplane processing unit). The ConnX D2 DSP engine utilizes two-way SIMD (Single Instruction, Multiple Data) instructions to provide high-performance on vectorizable C code.

The ConnX D2 DSP engine is also implemented with an improved form of VLIW (Very Long Instruction Word) instructions that delivers parallel performance without the code size bloat associated with most VLIW DSPs. This allows for parallelization of code across the two MACs/ALUs when vectorization is not feasible. This choice of vectorization or parallelization is used extensively by the compiler for fast performance on any algorithm.
