Hello. I have FlexRIO board PXIe-7966R. I'd like to calculate polynom of input data: 0.2139*x^3 - 0.0684*x^2+0.9524*x+0.0085 , where x - is I16 input data.
But i have a problem, that this calculating takes a lot of time - 20MHz. I'd like to execute this operation in single cycle timed loop with 125MHz clock. How can i optimize this operation?
