Embedded Target for Texas Instruments C6000 DSPs

DSP/BIOS Configuration File

DSP/BIOS projects all have a file with the extension .cdb. The file contains the DSP/BIOS configuration information for your project, in the form of objects for instrumenting and scheduling tasks in the program code. Included in any DSP/BIOS project might be:

• Log (LOG) objects for logging events and messages (replace the *printf statements, for instance)
• Statistics (STS) objects for tracking the performance of your code
• A clock (CLK) object for configuring the clock on your target, and various memory functions
• Hardware and software interrupt (HWI, SWI) objects that control program execution
• Other objects you use to meet your needs.

Your TI DSP/BIOS documentation can provide all the details about the objects and how to use them. In addition, your installed software from TI includes tutorials to introduce you to using DSP/BIOS in projects.

Not all of the DSP/BIOS objects get used by the code you generate from the Embedded Target for TI C6000 DSP. In the next sections, you learn about which objects the Embedded Target uses and how. Of course, you can still add more objects to your code through Code Composer Studio. Note, however, that if you add additional DSP/BIOS objects beyond those provided by the Embedded Target for TI C6000 DSP, you lose the additions when you regenerate your code from your Simulink model.
