Santa Clara, Calif. Tensilica, Inc. has added the Dolby Digital Consumer Encoder (DDCE) and Dolby Digital Compatible Output (DDCO) 5.1-channel encoders to its Xtensa HiFi 2 audio engine codec library. These encoders enable manufacturers to design consumer devices including Blu-ray Disc players, HD DVD players, portable devices and camcorders, which support Dolby 5.1-channel surround sound as well as next-generation high-definition (HD) video technologies.
Tensilica's highly efficient Dolby Digital 5.1-channel encoders are optimized for low-power operation, requiring just 60 MHz to encode at 48 kHz, 640 kbps. This reduces the overall power demands of the audio system-on-chip (SOC), resulting in lower cooling costs through less expensive packaging, heatsinking and elimination of noisy fans, said Tensilica.
Availability: The Dolby Digital Plus 5.1-channel encoder is available for shipment now to all Dolby-approved licensees of Tensilica's Diamond Standard 330HiFi or the Xtensa HiFi 2 Audio Engine.
