2.1.2 Digital Signal Processing

The DSPLIB library contains several low-level digital signal processing functions 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. The following subsections shows performance results for some of the frequently used functions in the digital signal processing domain.
