8.3.5 Firmware components Page
The Firmware components page includes all of the firmware components (also referred to as "overlays"
or ULDs) that are to be supported by the system being designed. This includes all decoders, matrix
processors, virtualizers, and post processors grouped by category.

Support this firmware component — Check box used to select support for the firmware component
highlighted on the left.
Composer project — List of DSP Composer projects that have been saved in the current project's
directory.
Uld file path — Specifies the ULD search path. If the filename contains '*', then the latest version of the
ULD will be used, otherwise the specific version will be used
Configs — One or more .cfg file definitions. Each .cfg definition is simply the name of a .cfg file. The
filename will be searched for in the directories specified by the CFG search paths specified in the Search
paths page. The files are concatenated to form a single set of control messages that constitute the "mode"
The mode .cfg files for a particular ULD should come from the different snapshot subdirectories from the
deliverables generated in a DSP Composer project that contains this ULD. The .cfg file that is used is the
one that matches the ULD. For example, if the modes are for the ac3 decoder, the .cfg files would be the
“decoder_ac3.cfg” files from the various snapshot subdirectories in an ac3 project deliverables folder. The
mode should also include any ULD-specific .cfg files from the preKickstart subdirectory of the project
deliverables folder, if any. For most modules there are no such .cfgs, but for the HD decoders there
usually are.
Snapshot — List of snapshots created in DSP Composer for this project.
