C6678 question about libraries mathlib and dsplib CODE_SECTION definition.

Other Parts Discussed in Thread: MATHLIB

Hi,

I'm using mathlib and dsplib and I saw that TI defines always CODE_SECTION in the routine, for example in the function divsp_i, that you wrote:

#pragma CODE_SECTION (divsp_i, ".text:optci");

1.- Please could you explain why did you define for every function its own CODE_SECTION like I wrote above?

2.- Please, could you tell me what are the beneficts of linking the optci in text and where the text must be linked?

Thanks

C. Garcia.

Hi Garcia,

This will ease your optimization where you would like to have part of your code closer to the core, so if you are using this function and you want to optimize your code you will put it in L2 or L1P (define in the linker),

Thanks,

It is used in every function in order to support C++. Please see:
