![]() ![]() This table highlights example SHARC processors and expected MIPS performance.The Dolby Pro Logic IIz Decoder on SHARC is provided with an API consistent with other audio decoder and post-processing modules produced by ADI. The module has no dependencies on processor peripherals or registers, adding greater system flexibility and ease of use. It contains a standard C-callable ‘push’ API with the added flexibility using ‘pull’ (or ‘poll’) by adding a light wrapper. ![]() The Dolby Pro Logic IIz Decoder takes up to 7.1 input channels and outputs up to 9.1 audio channels. ![]() The Dolby Pro Logic IIz decoder operates on PCM data received either through analog/digital input channels or from a decoder module. Both modules have been highly optimized to run on the Analog Devices SHARC processor family and have been certified by Dolby to be used for Dolby Pro Logic IIz processing. These are compliant with Dolby specifications and have been rigorously tested. #Dolby pro logic ii decoder software software#The Dolby Pro Logic IIz Decoder delivery from ADI consists of the “Dolby Pro Logic IIz Decoder” and “Dolby Pro Logic IIx Decoder” software modules. Dolby Pro Logic IIz can be used to expand 5.1-channel material or even stereo material to be reproduced by “7.1 Height” or “9.1” systems. These two channels drive two speakers positioned above the front left and right speakers. Multi-channel: Fully re-entrant and multi-instancing capableĭolby Pro Logic IIz is an extension of Dolby Pro Logic IIx that provides two additional “front height” output channels.Output Status: Sample rate, number of output channels, number of output samples per channel, and output channel configuration.Output buffer samples per block: Configurable and dependent upon input block size (7 * X, where X is input block size).Output format: 32-bit floating-point ranging from -1.0 to 1.0, up to 7 channels, non-interleaved.Input format: 32-bit floating-point ranging from -1.0 to 1.0, two channels, non-interleaved.Release Format: Object libraries for Dolby Pro Logic IIz.No dependencies on processor peripherals or registers. Compliance: Dolby test/certification requirements for Dolby Pro Logic IIz. #Dolby pro logic ii decoder software code#
