1.3.1. SinCos Function

Computes the sine and cosine of angle a.
Figure 1. SinCos Function

The function supports two configurations, depending on the sign attribute of a:

  • If a is signed, the allowed input range is [-π,+π] and the output range for the sine and cosine is ∈[−1,1].
  • If a is unsigned, the IP core restricts the input to [0,+π/2] and restricts the output range to [0,1].
