Figure 8-12. DSP Composer Sample Project, “WhizBang Model” Directory Structure:
8.6.1.2 Creating Projects
A total DSP Condenser system design includes all of the firmware components (also referred to as
“overlays” or ULDs) that are to be supported by the system under design. This includes all decoders (for
example, AC3, TRUEHD, PCM, HDCD), matrix processors (for example, NEO6, PL2X), virtualizers (for
example, Dolby Headphone), and post processors (for example, PEQ, Bass Manager, Delay).
Because DSP Composer only supports projects that include one decoder, matrix processor, virtualizer,
and PPM, multiple Composer projects must be used to specify all of the settings for all of the firmware
components in the entire system design. Each project should be saved in the following directory:
c:\CirrusDSP\DSPCondenser\projects\<model>\cpa_files
The number of project (.cpa) files required to represent the entire system design is, of course, design-
dependent. Designers may choose to create a separate project for capturing settings for each
component, or combine multiple components in a single project. For example, a project that includes AC3
must also have a PPM in order to compile, so SPP would be included. Snapshots that are captured from
this project will include settings for AC3 and all of the modules in SPP. Regarding SPP configuration
settings, the system designer can choose either of these options:
• Consider the SPP settings generated from this project as significant, that is, to be included in final
system.
• Ignore SPP settings generated from this project
DSP Condenser allows either option.
