4.1 Introduction
4.2 Basic Application Download and System Configuration - PCM
With the exception of the power selection jumpers, the CRD49530 is configured exclusively through
software. The DSP Composer™ software is a graphical user interface (GUI) that is used to program the
CS4953xx DSP, and to configure the CRD49530. This section provides basic instruction for using the GUI
to control the CRD49530, but detailed information can be found in the DSP Composer™ User’s Manual.
Both the DSP Composer™ software, and the User’s Manual for the software package will be provided by
your local Cirrus Logic representative.
Follow the instructions in
the USB drivers on your PC and launch CS4953x version of DSP Composer (the GUI used to control the
CRD49530).
After following the instructions in
the DSP Composer main window will appear as shown in
Figure 4-1
CRD49530. The blocks shown in the main window of DSP Composer can be selected from the folders in
the left-hand window pane, and then connected together by “wires” to indicate the processing path as
shown.
The “Audio In” and “Audio Out” blocks represent the hardware ports that need to be configured. The
“Audio In” block is used to select the S/PDIF Input or Analog input that is to be processed, and configure
the digital audio format for the CS8416, CS42448 ADCs, and the CS4953xx DAI port. The “Audio Out”
block is used to configure the digital audio format for the CS4953xx DAO port, the CS42448 DACs, and
enable or disable the S/PDIF TX output of the CRD49530.
