Fixed Point Math - specific library to use?

[RiTa_288331]

I understand that the PSOC math library can be added with the "m" option in the linker.  However, I'm looking on Cypress' website for fixed point math examples, and I don't see any.

   

--> Is there an IQ math, or Q notation math, that is "PSOC approved", or do I need to import an external fixed point math library?

        You have to use external fixed-point library like CMSIS etc. http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dai0033a/index.html http://www.mbedded.ninja/programming/general/fixed-point-mathematics
