Embedded Target for Texas Instruments C6000 DSPs

DSP/BIOS and Targeting Your C6000 DSP^TM

When you use Real-Time Workshop to generate code from the Simulink model of your digital signal processing application, you can choose to include the DSP/BIOS features provided by the Embedded Target for TI C6000 DSP in your generated code.

By electing to include DSP/BIOS in your generated project, the Embedded Target for TI C6000 DSP adds a DSP/BIOS configuration file (with the filename modelname.cdb) to your project, and adds the the following files as well:

• modelnamecfg.s62--contains the DSP/BIOS objects required by your application and the vector table for the hardware interrupts.
• modelnamecfg.h62--the header file for modelnamecfg.s62.
• modelnamecfg.h--model configuration header file.
• modelnamecfg_c.c--source code for the model.
• modelnamecfg.cmd--the linker command file for the project; adds the required DSP/BIOS libraries and the library RTS6201.lib, or the run-time support library for your target.

Thus the executable code and source code you generate when you use the DSP/BIOS option is not the same as the code generated without DSP/BIOS included.

Rather than having you incorporate the DSP/BIOS files manually when you create your application, as you would if you used Code Composer Studio alone, or another text editor, the Embedded Target for TI C6000 DSP starts from your Simulink model and adds the DSP/BIOS files automatically. As it adds the files it:

• Configures the DSP/BIOS configuration file for your model needs
• Sets up the objects you need to analyse your program while it runs on your target
• Handles memory mapping to optimize your code based on the blocks in your model
