TMS320F28069F: IQmath function : __IQmpy(A,B,12)

Part Number: TMS320F28069F
Other Parts Discussed in Thread: MOTORWARE

Hello,

I have a question on the motorware software.

Specifically it is on the function of _IQ12mpy(A,B), which is used extensively in HAL_readAdcData().

It is defined in the file of IQmathLib.h as follows:

#define  _IQ12mpy(A,B)  __IQmpy(A,B,12)

I can not find out the prototype for the function of __IQmpy(A,B,12).

What is the meaning of __IQmpy(A,B,12)?

It seems like a IQmath function.

Which file should I refer to in order to understand it.

Thank you for your guidance.

With regards,

G. Kim
