TMS320F28388S: Is a CLA Memory Assignment for Writeable RAM Necessary?

Ed Sanders

Tool/software:

Greetings,

If a CLA application is using an LS Memory for the code it will execute and doesn’t need to use an LS RAM for writeable memory, is it still necessary to assign one? (It would use the message RAMs for the data it needs/generates.)

Thank you,

Hi Ed,

I'm not sure if I understand your question. Do you mean do all of the LSRAM's have to be defined in the MEMORY area of the linker cmd file? Technically no, if they aren't being used to define a section (they would still be present in physical memory though).

Best Regards,

Delaney

Hi Delaney,

The hope is to use an LSRAM for the code which the CLA will execute, and the msg RAMs for the writeable area. So the use of the CLA would only consume a single LSRAM. Is that possible?

Thank you,

Hi Ed,

Yes, that is possible. As long as all of your CLA memory (including the full program, data memory, and constants etc.) can fit into one LSRAM, then you only need to allocate permissions for that one LSRAM to the CLA.

Best Regards,

Delaney
