Tensilica Announces Industry’s First MP3 Decoder Under 6 MHz

Tensilica has optimized the MP3 decoder for its Xtensa HiFi 2 Audio Engine and Diamond Standard 330HiFi processor core. This MP3 decoder now runs at the lowest power and is the most efficient in the industry, requiring just 5.7 MHz when running at 128Kbps, 44.1 KHz and dissipating 0.45 mW in TSMC’s 65nm LP process (including memories). This makes Tensilica’s Xtensa HiFi 2 Audio Engine ideal for adding MP3 playback to cellular phones, where current carrier requirements are for 100 hours of playback time on a battery charge, and increasing to 200 hours in the near future.

This 5.7 MHz requirement includes the entire MP3 decode functionality, including MPEG container parsing and variable length decoding (VLD, also known as Huffman decoding). Some competing offerings are merely accelerator blocks that exclude portions of the complex control code in MP3 such as VLD, and thus rely on a processor to perform VLD decoding. Tensilica’s 5.7 MHz figure is all inclusive.

New Energy Estimator Tool Guides Designers to Energy-Efficient SOC Architectures

To address the growing need to pro-actively reduce power consumption in embedded systems, Tensilica announced the Xenergy estimator, a unique energy estimator for both Xtensa configurable processors and Diamond Standard processors. By using the Xenergy tool to optimize for energy early in the SOC design cycle, designers can cut processor and local memory energy requirements by up to half by making intelligent design trade-offs.

“Xenergy will naturally appeal to designers of portable, battery-driven devices such as cellular phones and personal media players, but also to designers of complex SOCs in home entertainment and networking devices where heat is becoming a huge issue,” stated Chris Rowen, Tensilica’s president and CEO. “Tensilica is the first company to provide a realistic way to easily estimate the overall energy impact of different processor configurations and extensions together with application code tuning on each processor with its memory subsystem. The improvement in power at the architectural level is quite dramatic and productive, often dwarfing the power savings painfully achieved at the RTL and physical design levels.”

LG Electronics currently uses Tensilica’s Xtensa processors for video and control processing in their Terrestrial Digital Multimedia Broadcasting (T-DMB) phone.

“We picked Tensilica’s Diamond Standard 330HiFi Audio Engine for three main reasons: low power, availability of a wide range of audio codecs, and our strong relationship with Tensilica’s technology in our DMB group,” stated Dr. Woo-Hyun Paik, Vice President of LG. “Tensilica’s Audio Engine is a proven solution, ready to drop into our next-generation designs.”

Tensilica Licenses Xtensa LX2 Configurable Processor to Marvell

Marvell has taken a company-wide license to Tensilica’s Xtensa® LX2 configurable processor. This agreement was driven in part by Marvell’s successful use of Tensilica’s earlier Xtensa processors in high-volume printer applications, Yukon® gigabit Ethernet products, and LinkStreet® router products. Marvell plans to use the Xtensa LX2 configurable processor in various products throughout the company.

“By using Tensilica’s Xtensa processors in three very high-volume product lines, Marvell is able to take advantage of the extreme flexibility that these configurable processors provide for our design teams,” stated Alan Armstrong, vice president of marketing for Marvell’s Storage Business Group. “Our design teams will be able to deploy Tensilica processors in a broad range of roles, including many non-traditional design sockets within datapath and dataplane functions.”

Tensilica Adds G.729AB Speech Codec for HiFi 2 Audio Engine

Tensilica introduced another codec for its popular HiFi 2 Audio Engine and Diamond Standard 330HiFi processor core which are specifically optimized for audio in mobile multimedia devices. The G.729AB speech codec, mostly used in Voice over IP (VoIP) applications, is fully compliant with ITU (International Telecommunication Union) specifications for the G.729 standard with annexes A and B. As an ITU standard, G.729 is one of the most tested and lowest bandwidth digital speech transmission standards.

Epson Licenses Xtensa LX for Printer Designs

Seiko Epson Corporation (“Epson”) has closed a long-term, multi-year license of Tensilica’s Xtensa family of configurable processor cores for Epson’s new REALOID printer engine chip. The first generation REALOID chip is used in Epson’s latest photo-capable inkjet printers and multi-function printers (MFPs), including the newly announced Colorio PM series MFPs. The Epson Stylus Photo R380 Ultra High-Definition REALOID-based printer is now available in the US. The strategic relationship also includes next-generation REALOID designs.

Epson’s engineers added Tensilica Instruction Extensions (TIE ) to customize several different Xtensa LX processors, each for a unique step in the inkjet image processing chain. By utilizing unique features of the Xtensa LX processor which allow direct high-speed data communication between the processors and thereby avoid the time delays of bus-based data traffic, Epson’s engineers were able to reduce the time required to print a single page to less than a third of that required by previous generation inkjet printers. These new printers can print borderless 4 x 6 photos as fast as the highest printing speed for black and white text.

CoWare’s Platform Architect Fully Supports Tensilica’s Configurable and Standard Processors

CoWare and Tensilica announced they have collaborated to deliver a comprehensive ESL design environment with CoWare’s Platform Architect for Tensilica’s processors. CoWare will distribute a SystemC-based Processor Support Package (PSP) with the flexibility to match all configurations of Tensilica’s Xtensa configurable processor family as well as Tensilica’s Diamond Standard family of processor cores.

Design engineers can now use CoWare’s Platform Architect ESL environment to do full architectural exploration, design verification, and software development when designing with Tensilica’s Diamond Standard processors and Tensilica’s highly-configurable Xtensa processors. This collaboration provides a huge productivity boost for SoC designers, as it not only speeds the design process, but also enables parallel development of the hardware and software.
