Re: inverse sine FPGA

I am confused why you are using a look up table. There is an arc sine function built into LabVIEW. You can find in the Functions Pallet group -> Mathematics -> Elementary & Special Functions -> Trigonometric -> asin

I modified and attached your vi with the asin function in it. If you need to shift the value or do a unit change, you can do it to the output of the asin function.

The built-in asin function cannot be implemented inside FPGA VI. That's why LUT is necessary.
