Question asked by xh sun on Feb 12, 2020

I have 1 input signal for sin and cos. I want to use arctan calculation to convert it into angle data. I need to find a chip with arctan operation function? And I need to know how long does the arctan operation take?

1、Please recommend a chip with CORDIC module?

2、Please give the time it takes to run the arctan function once
