Mapping code to IRAM
Added by Marc Lichtman over 12 years ago
Hey All,
I am using CCS4 and SYS/BIOS to program the DSP core in the L138, and I am trying to figure out how to specify the linker option so that a certain C function gets mapped into IRAM, instead of DDR. When I look at the C/C++ Build settings in CCS and go to linker settings, I dont see anything that would let me do this. I tried to make a new .cmd file that contained the code below, and add it as an input command file, but it did not seem to work. Any help would be much appreciated.
SECTIONS
{
.text:myfunc > IRAM
}

Hi Marc -
I'm not sure we will have the answer to this question as it's really a TI question. While we're waiting for a response from my team you may also wish to post it on the TI e2e forums.

Hi Mark
You could try the #pragma CODE_SECTION(<function name>, "mysect") (In C++ you omit the function name and places the pragma before the declaration). You will probably have to define your own section in the CMD file.
Look at the TMS320C6000 Optimizing Compiler User’s Guide
