9.2.7 DSP Manager API Group
The DSP Manager API Group shows the current settings in the DSP Manager API. See the CS4953x4/
CS4970x4 System Designer’s Guide, “Overview of Common Firmware Modules” for additional
information.
After a connection occurs (if a user changes any values), the values show up in red. Only the DSP
Manager API Registers whose corresponding “Combo” box have changes are updated when the “Apply”
button is pressed.
If the DSP Condenser starts with the DSP image information, the Decoder, Decoder Mode, MPM, MPM
Mode, VPM, VPM Mode, PPM, and the PPM modes are populated with the names of the .ulds as shown
in
Figure 9-12 .
Figure 9-12. DSP Manager API Group with Image Information
If the DSP Condenser is started without image information (that is, “Runtime GUI Standalone” mode),
these combo boxes are filled with hexadecimal values as show in
Figure 9-13 .
