The folks at Tensilica say that they have added the Dolby Pro Logic II and Pro Logic IIx decoders to their audio codec library for their Xtensa HiFi 2 Audio Engine, which is one of the most popular commercial audio cores for system-on-chip (SOC) designs.
Both Dolby Pro Logic decoders are essential sound processing technologies employed in home theater AV receivers. Dolby Pro Logic II creates a captivating 5.1-channel surround sound experience from any stereo movie, music, TV, or game audio source. Dolby Pro Logic IIx extends the sound experience up to a full 7.1-channel configuration for highly realistic, natural surround sound.
For anyone designing a chip for home and automotive entertainment systems, Tensilica's HiFi 2 Audio Engine provides a proven, approved, "drop-in" audio solution. By adding Dolby Pro Logic II and IIx decoders to their HiFi 2 audio codec library, Tensilica can satisfy the needs of designers developing SoCs for home entertainment and multichannel in-car audio systems.
Tensilica's HiFi Audio Engine is a fully programmable processor core optimized for audio applications, with a library of over 50 of the most popular audio software packages. Other Dolby approved packages include: Dolby Digital Decode, Dolby Digital Creator Encode, Dolby Digital Compatible Output Encode, Dolby Digital Plus 5.1 and 7.1-channel Decode, and Dolby TrueHD Decode.
The Dolby Pro Logic II and IIx decoders are available for shipment now to all Dolby approved licensees of Tensilica's Diamond Standard 330HiFi or the Xtensa HiFi 2 Audio Engine.
