Other Parts Discussed in Thread: MSP430F5438A

Hello,

I'm working with the CCS 5.3 on the msp430f5438a.
format EABI , with floating point calculation in my code.
While I make my data processing on the FLASH, I get the following comment:
------------
# 1531-D (ULP 5.2) Detected floating poing operation (s).
Recommend moving them to RAM during run time or not using as
these are processing / power inetnsive
----------

Then there is no meaning if I run the code in RAM or FLASH memory.
it run in the same speed.

and i work with EABI format, which is floaing point percision of 64 bit.
so percision is not the problem.

so what is the meaning of that comment?
and what the problem can be?

Thanks

Hi,

please see here: http://processors.wiki.ti.com/index.php/Compiler/diagnostic_messages/MSP430/1531

It is just a "advise" message from the ULP advisor to inform you that if you are designing application where low power consumption is a must, you need to consider another way to do the computation rather than using the floating point arithmetic since it will take up a long processing.

If you can't find any other way, than of course you can stick with it.

thanks.

but how to suppress this remark?

I try the both options: --diag_suppress = 1531

and the : -pds = 1531

none of them help.

so , what wrong? how to suppress this remarks?

thanks.

Hi,

you need to go to "Project" -> "Properties" -> "Build" -> "MSP430 Compiler" -> "ULP Advisor" as follows:

you can check/uncheck the rules to activate/deactivate the ULP advisor messages.
