CEVA udvider familien af DSP-kerner

CEVA, der har erobret en hovedrolle på markedet for DSP-kerner, introducerer ny kerne, der optimeret med hensyn til audioydelse og fleksibilitet, ligesom en bred vifte af audiocodes er understøttet (in english).

CEVA, a leading licensor of silicon intellectual property (SIP) platform solutions and DSP cores, today announced the latest addition to its CEVA-TeakLite-III DSP architecture. The CEVA-TL3211 is an advanced DSP targeting the growing needs for low cost smartphones and high-definition (HD) audio features within digital televisions (DTV), set-top-boxes (STB) and Blu-ray Disc players.

According to CEVA the new cores delivers the industry’s highest levels of performance, power efficiency, user flexibility, and smallest memory footprint to address the requirements of 2G/3G modems and advanced audio processing, including fully-certified HD audio codecs from Dolby and DTS. The new core has already been adopted by a Tier-1 semiconductor vendor.


The new CEVA-TL3211 processor is compliant and code compatible with the CEVA-TeakLite-III architecture that was recently named the industry ‘best all around audio processor’ in an independent report1. It is a 32-bit audio DSP running at 1GHz with a silicon footprint of only 0.2mm2 when implemented on a 40nm process node.

Specifically benefitting the DTV and STB markets, the processor runs a complete DTV use-case in less than 200 MHz, leaving ample headroom for vendors to run various post-processing functions on the same core, thereby reducing overall cost. For low cost smartphones, the CEVA-TL3211 allows an efficient integration of baseband processing with application processing related needs like HD audio, and voice enhancements such as noise cancellation and beam forming.

The CEVA-TL3211 core is fully backwards compatible with earlier CEVA-TeakLite families, including CEVA-TeakLite, CEVA-TeakLite-II, CEVA-Teak and the CEVA-TL3210, thereby allowing licensees of these cores to easily reuse their existing code. The processor further reduces development time through its fully cached memory subsystem and CEVA’s production-proven application optimizer and software development environment.

On top of its industry-leading performance enabling simultaneous multi-codec and multi-stream processing, the flexible CEVA-TL3211 core offers:

• Full support for the latest HD audio codecs required for premium quality sound. These include the Dolby MS10 and MS11 Multistream codecs for next generation DTV and STB designs, as well as the complete DTS-HD audio codecs;

• A flexible fully cached design (code and data), including L2 cache support, that allows rapid algorithm development and supports the use of real-life system DDR constraints, contributing to lower cost of the end product;

• CEVA’s innovative Power Scaling Unit supporting clock and voltage scaling, reducing power consumption, lowering heat dissipation, and allowing cheaper IC packaging;

• Full duplex AXI buses for lower power, higher performance and easier integration into modern SoCs;

• A robust software development environment to ease software migration and facilitate C-level programming

- The new CEVA-TL3211 extends the most popular and extensively deployed DSP architecture, with more than 100 design wins,1.5 billion devices shipped to-date and more than 90 fully optimized audio and voice codecs. We have leveraged our production-proven CEVA-TeakLite-III DSP architecture for the specific needs of next-generation audio and voice applications, such as DTVs, STBs and smartphones, providing the industry’s most powerful audio and voice processor available to-date, says Eran Briman, vice president of marketing at CEVA.

- We have a track record of working with leaders in audio technology, and our innovative features such as the solution’s power scaling unit, its efficient memory utilization and its substantial audio processing capabilities allow product designers to meet their market requirements faster and with lower risk.
