TMS320F2812: 64 bit root function

Part Number: TMS320F2812
Other Parts Discussed in Thread: C2000WARE

Dear TI engineers,

I want to use 64bit root calculation in TMS320F2812, but I only see 32bit root function in IQmath lib. 

So, if I need to do 64bit root, shall I write a function by myself? Or do you have some faster way?

Looking forward for your words,

coke.

    Hello Coke,

    The IQmath library only contains 32-bit fixed-point data types and functions. What you're saying is correct, if you want to do anything with a 64-bit number that's not with floating point, then you will have to write the function yourself, we unfortunately do not offer any libraries for 64-bit fixed-point operations, at least not from what I could find in the compiler or C2000Ware libraries.

    Best regards,
