Tool/software: Code Composer Studio
Hello everyone,
I have just started working with the DSP TMS320F28377D and I do not have much experience. I saw in the datasheet that it has a trigonometric math unit (TMU) which can execute operations shown in the table below. My question is: how to use it?
In a code example from TI I found this code line:
park1.Sine = __sinpuf32(park1.Angle);
Is this code already using the TMU?
Thanks
Correct. This is an intrinsic which translates to the TMU instruction SINPUF. You can read about it on p.157 of the C compiler user's guide, here:
In general, if your device has a TMU you can tell the compiler to generate instructions by enabling the --tmu_support compiler flag. To do this, right-click on the project name in your CCS explorer window, and select "Properties". Go to "CCS Build -> C2000 Compiler -> Processor Options", and use the drop-down box next to "Specify TMU Support".
Regards,
Richard
