What Are the Best Methods to Compute Arctan2 on an FPGA? FPGAs are great for prototyping and reducing power consumption. However, they also have limitations. One such limitation is with division, subtraction, and multiplication operations. These operations require a clock cycle to complete and FPGA logic gates use a lot of power. So, how can we compute arctan2 with an FPGA? Let's explore. Arctan2 is the inverse trigonometric function of the tangent (tan). It takes two inputs: A and B (which represent the lengths of the sides of a right triangle). ...
