4.3 OS Manager in DSP Composer

Most configuration information described in Section 4 can be controlled in DSP Composer. The OS Manager indices are

available in the Audio In, Audio Out, and System blocks. To insert these, simply drag the Audio In, Audio Out, and System

blocks to the workspace. When the Audio In, Audio Out, and System blocks are on the workspace, the pre-kick and runtime

controls are accessible by double-clicking in the corresponding blocks. Runtime controls such as PCM Config, Autodetect,

and Autoswitch can be enabled by double-clicking the System block, as shown in Fig. 4-2.

Figure 4-2. Autodetect and Autoswitch

The controls are adjustable during runtime to interact with the DSP in a similar way as would a host microcontroller in an

actual system. Fig. 5-2 shows that when you initially drag the Audio In block onto the workspace, the Audio In Device

Properties automatically pops up, prompting to the user to select the input source and data format. This is also accessible

by right-clicking the Audio In block.
