2.1.3 Mathematical Operations

The MATHLIB library contains several low-level functions for mathematical operations such as trigonometric, power and exponent which are implemented on the C7x DSP. This library is included in the FREERTOS-SDK of AM62D. Instructions to reproduce and run these modules are included in the documentation folder of the library. Table 2-6 shows performance results for some of the frequently used mathematical functions in MATHLIB library.
