Figure 4-1. ADC In / DAC Out Example

4.2.1 System Block

All designs must contain the System block. In DSP Composer, when you drag the System block onto the

workspace, the dialog box shown in Figure 4-2 is displayed. This dialog box provides options for selecting

the Target chip associated with the development board, the Firmware version (memory map), Core

Speed, Reference Clock Frequency (Ref. clock freq.), and the Autodetect Fs.

Note: Leave the Autodetect Fs default value as "None" unless the application note for a specific

firmware module used in a Composer project provides a setting that differs from the default

value.
