TMS320F28375D: Does the RPT and NOP instruction stall the CLA?

TMS320F28375D: Mixing assembly instruction and C code in CLA code

Hi,

I have a C code written for the CLA task. And I wish to write asm instructions as well.

I want to toggle GPIOs which are gate signals to a power converter. In order to implement delay I want to include the asm("MNOP") instruction in the CLA C code in order to add a timed delay (in ns) between two GPIO toggles (effectively implementing deadband control).

Are there any implications of doing so that I should be aware of.

Second question is about the timing requirement -

I perform a floating point calculation in the cla C code. Will it be worthwhile to try the same calculation in assembly language in terms of execution speed.

Thanks in advance.

Regards,

Anurag

    Hi Anurag,

    You can mix assembly code in C. That should not be problem

    On your seconf question, rather than writing the asm code directly, I would recommend you write in C, take a look at the compiler generated asm file, and optimize as needed. You can also make use of CLAMath library
