16 CORDIC co-processor (CORDIC)
16.1 CORDIC introduction
The CORDIC co-processor provides hardware acceleration of certain mathematical
functions (mainly trigonometric ones) commonly used in motor control, metering, signal
processing and many other applications.
It speeds up the calculation of these functions compared to a software implementation,
making it possible the use of a lower operating frequency, or freeing up processor cycles in
order to perform other tasks.
