5 / 34 page CS4953xx Data Sheet 32-bit Audio Decoder DSP Family DS705PP3 Copyright 2008 Cirrus Logic 5 3. Code Overlays The suite of software available for the CS4953xx family consists of an operating system (OS) and a library of overlays. The overlays have been divided into three main groups called Decoders, Mid-processors, and Post- processors. All software components are defined below: 1. OS/Kernel - Encompasses all non-audio processing tasks, including loading data from external memory, processing host messages, calling audio-processing subroutines, error concealment, etc. 2. Decoders - Any Module that initially writes data into the audio I/O buffers, e.g. AC-3®, DTS, PCM, etc. All the decoding/processing algorithms listed below require delivery of PCM or IEC61937-packed, compressed data via I2S- or LJ-formatted digital audio to the CS4953xx. 3. Mid-processors - Any module that processes audio I/O buffer PCM data in-place before the Post- processors. Generally speaking, these modules alter the number of valid channels in the audio I/O buffer through processes like Virtualization (n 2 channels) or Matrix Decoding (2 n channels). Examples are Dolby ProLogic IIx and DTS Neo:6. 4. Post-processors - Any module that processes audio I/O buffer PCM data in-place after the Mid-Processors. Examples are Bass Management, Audio Manager, Tone Control, EQ, Delay, Customer-specific Effects, Dolby Headphone/Virtual Speaker, etc. The overlay structure reduces the time required to reconfigure the DSP when a processing change is requested. Each overlay can be reloaded independently without disturbing the other overlays. For example, when a new decoder is selected, the OS, mid-, and post-processors do not need to be reloaded — only the new decoder (the same is true for the other overlays). Table 2 below lists the firmware available based on device selection. Please refer AN288 CS4953xx Firmware User’s Manual for the latest listing of application codes and Cirrus Framework™ modules available. |
