Build for Hexagon Applications DSP (aDSP)


There are two DSPs available for programming on VOXL (Snapdragon 821). The Applications DSP (aDSP) and the Sensors DSP (sDSP)

The aDSP is a powerful digital signal processor to offload signal processing tasks from the CPU. It is most capable performing fixed-point computer vision compute offload.

The sDSP is well suited to work with I/O and has a real-time operating system QuRT.
