Figure 8-14. Sample Deliverables Directory Struction
When DSP Composer generates deliverables, the configuration parameters (.cfg file) for each firmware
component is saved into a separate file, with all .cfg files for a specific snapshot saved into a directory
named for the snapshot. These individual .cfg files will later be used by other DSP Condenser tools to be
incorporated into the Flash image.
For an example of how to create DSP Composer deliverables, follow Steps 1 to 5 in the section,
“Creating DSP Composer Deliverables.”
