Sunplus Technology Co. Ltd has licensed the CEVA Inc.'s CEVA-TeakLite-III DSP core for its next-generation STBs, HDTV and Blu-ray disc chipsets.

Sunplus is integrating CEVA's high performance DSP to power the most demanding high-definition audio requirements. The agreement expands CEVA's relationship with Sunplus, whose subsidiary Sunplus mMedia powers their latest generation SPMP8000A portable media player chipset with CEVA's MM2000 portable multimedia solution.

TzuHsin Wang, director, product design, home entertainment business unit, of Sunplus, said, "By exploiting the performance, integration and cost advantages of the CEVA-TeakLite-III DSP in the design of our Blu-ray SoC, we have developed a powerful design that addresses the most demanding requirements of high definition audio today."

"This agreement marks CEVA's continued expansion into the home entertainment market and being designed into a Blu-ray SoC from an industry leader like Sunplus is a validation of the performance, die size and ease of development benefits offered by the CEVA-TeakLite-III DSP architecture for high definition audio applications," said Eran Briman, VP corporate marketing of CEVA.

CEVA-TeakLite-III is a third-generation DSP architecture based on the broadly adopted TeakLite family of DSP cores. As the engine powering CEVA's HD audio solution, the CEVA-TeakLite-III DSP core features native 32bit processing, including 32bit multiplier with 72bit accumulation for full data precision. In addition, its strong bit-manipulation capabilities for stream processing and 32bit FFT support enable a highly efficient implementation of audio codecs. A well-balanced 10-stage pipeline allows the DSP to support high speed implementations, making it ideal as a single-core for most demanding HD audio use-cases. CEVA-TeakLite-III is available with a range of optimized HD audio codecs supporting from 2 channels up to 7.1 channels with various bit-rates. Audio codecs supported include: MP3, AAC-LC, HE-AAC, WMA, AC-3, RealAudio, Dolby Digital Plus, Dolby TrueHD, DTS, DTS-HD MA, DTS-HD HR and others.
