CEVA Inc. announced the latest addition to its CEVA-TeakLite-III DSP architecture. The CEVA-TL3211 is an advanced DSP targeting the growing needs of low cost smartphones and high-definition (HD) audio features within digital televisions (DTV), set-top-boxes (STB), and Blu-ray Disc players.

The CEVA-TL3211 DSP core is compliant and code compatible with the CEVA-TeakLite-III architecture, which was cited 'best all around audio processor' in an independent report, done by Joseph Byrne and Linley Gwennap, published March 2010.

The CEVA-TL3211 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 device implements a complete DTV use-case in less than 200MHz, 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 also enables an efficient integration of baseband processing along with application processing related needs like HD audio and voice enhancements such as noise cancellation and beam forming.

The CEVA-TL3211 DSP core is fully backwards compatible with earlier members of the CEVA-TeakLite family, including the CEVA-TL3210 DSP core, CEVA-Teak, CEVA-TeakLite, and CEVA-TeakLite-II DSPs, allowing licensees of these earlier DSP cores to easily reuse their existing code.
