4.1 Introduction
4.2 Basic Application Download and System Configuration for
The DSP Composer™ software is a graphical user interface (GUI) that is used to program the CS485XX
DSP, and to configure the CDB48500. With the exception of the power selection and DAI input jumpers,
the CDB48500 is configured exclusively through software. This section provides basic instruction for
using the GUI to control the CDB48500, 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
install the USB drivers on your PC and launch DSP Composer (the GUI used to control the CDB48500).

CDB48500. 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, Analog input or USB input that is to be processed. It
configures the digital audio format for the CS8416, ADC side of CS42448 and the DAI port of the
CS485XX. The “Audio Out” block is used to configure the digital audio format for the DAC side of the
CS42448, the DAO port of the CS485XX and enables or disables the S/PDIF TX output port of the
CS485XX.
