CCS/EVMK2H: Accessing Control Registers (DNUM)

Madeleine Tiu

Part Number: EVMK2H

Tool/software: Code Composer Studio

Good day,

We are currently testing the functionality of the DSP cores in EVMK2H.

As preliminary testing, we are writing a C program that could output a Hello World text on the console that is dependent on the core executing the code.

For example,

C66xx_0 would print Hello World 0,

C66xx_1 would print Hello World 1, and so on

But as a beginner we're having trouble reading the register contents in C.

It would be a great help if you could point me to the right resources.

Thank you very much.

Best Regards,

Madie Tiu

See the 7.5.3 The __cregister Keyword section of the TMS320C6000 Optimizing Compiler v8.2.x User's Guide. If you include the c6x.h the include file you will get a definition for reading DNUM as well as the other control registers.
