stage
Using the Cirrus Logic CS48DVx / CS49DV8
Controller GUI for Dolby Volume
The CS48DV2/6 ICs are programmed with the latest Dolby Volume firmware
using the Cirrus Logic proprietary GUI software development & evaluation tool
called Dolby Volume Controller. This same tool then configures the CS48DV2/6
through the SPI™/I
command to boot itself using firmware loaded from ROM within the CS48DV2/6
(starting with Rev B Silicon - available in April, 2008), or it may be downloaded
through the serial control port from either a master host microcontroller or an
external I
is responsible for downloading the specific hardware and software configuration
commands. All Dolby Volume parameters running on the CS48DV2/6 firmware
can be adjusted in real-time as well as allowing 6 different presets to be saved
and recalled easily, enabling very simple and quick “A/B” listening tests for the
target design.
