Part Number:TMS320C6678
Tool/software: TI C/C++ Compiler
Hello compiler experts
In my field we use a middleware to abstract the OS and HW archictecture and software applications are built on top of this middleware.
The HW is composed of DSP C6678.
The middleware is a library designed to run on this DSP.
Here are the compilation options I use to build the library:
-mv6600 --abi=eabi -mi10 --gen_func_subsections=on -Ooff -g
(we volontary choose to let the library fully debuggable)
By default the memory model is --mem_model:data=far_aggregates.
The application compilation options are:
-mv6600 --abi=eabi -mi10 --mem_model:data=far_aggregates
We put initialization code in DDR3 memory (because performance is not needed at initialization), other code is in L2 (for performance).
We notice quite a lot of trampolines call but I'm not worried about them due to some of the code being in DDR3.
I have read the Wiki on C6000 Memory models and the application report SPRAA46A
My questions are:
- Should I default to the "near" memory model for the library ?
- Should I use other important options for the library that I missed ? (do you have suggestions)
Thanks
Regards
Clement
