3. Code Overlays
The suite of software available for the CS470xx family consists of an operating system (OS) and a
library of overlays. The software components for the CS470xx family include:
1. OS/Kernel—Encompasses all non-audio processing tasks, including loading data from external
serial memory, processing host messages, calling audio-processing subroutines, error
concealment, etc
2. Decoder
—Any module that performs a compressed audio decode on IEC61937-packed data
delivered via S/PDIF Rx or IS input, such as Dolby Digital (AC3).
3. Matrix-processor—Any Module that performs a matrix decode on PCM data to produce more
output channels than input channels (2
n channels). Examples are Dolby Pro Logic IIx and
SRS Circle Surround II. Generally speaking, these modules increase the number of valid
channels in the audio I/O buffer.
4. Virtualizer-processor—Any module that encodes PCM data into fewer output channels than
input channels (n
2 channels) with the effect of providing “phantom” speakers to represent the
physical audio channels that were eliminated. Examples are Dolby Headphone 2 and Dolby
Virtual Speaker 2. Generally speaking, these modules reduce the number of valid channels in
the audio I/O buffer.
5. Post-processors—Any module that processes audio I/O buffer PCM data. Examples are bass
management, audio manager, tone control, EQ, delay, customer-specific effects, and any post-
processing algorithms available for the CS470xx DSP.
The bulk of standard overlays are stored in ROM within the CS470xx, but a small image is required
to configure the overlays and boot the DSP. This small image can either be stored in an external
serial FLASH/EEPROM, or downloaded via a host controller through the SPI/I2C serial port.
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 different post-processor is selected, the OS, does not need to be reloaded —
only the new post-processor.
Table 2 lists the different configuration options available. Please refer to the CS470xx Firmware
User’s Manual
for the latest listing of application codes and Cirrus Framework modules available.
See Table 3 which provides a summary of the available channels for each type of input and output
communication mode for members of the CS470xx family of DSPs.
