DEM
Overview
The DEM is a real-time system. It needs to retrieve waveform amplitude information (“samples”) from an analog-to-digital converter at precise intervals, do calculations with those samples, and perform timing operations
Features
1. Ten threads to carry out different tasks with different priorities to achieve hard real-time.
