DCORDIC
CORDIC processor
ver 1.16
OVERVIEW
The DCORDIC uses the CORDIC algorithm
to compute trigonometric, reverse trigono-
metric, hyperbolic and reverse hyperbolic
functions.
It supports sine, cosine, arcus tangent func-
tions for hyperbolic and trigonometric sys-
tems. Logarithm, square root and exponent
functions can also be computed. It supports
fixed point 24-bit numbers.
