Integrating Time-Triggered and Event-Triggered Communication in a Hard Real-Time System

The setup and verification of time-triggered communication systems are very tedious. Detailed process time information like the Worst Case Execution Time (WCET) must be gathered beforehand to determine the slot sizes such that no slot violations occur. For highly dynamical … Continue reading

Wireless Time-Triggered Communication using a Firefly Clock Synchronization Approach

In South-East Asia, huge swarms of fireflies synchronously emit light flashes to attract mating partners. The underlying principle can be used to implement a robust and scalable distributed synchronization approach in wireless sensor networks. In this work we implement the … Continue reading

Efficiently detecting a frequency using a Goertzel filter

The Goertzel algorithm detects a specific, predetermined frequency in a signal. This can be used to analyze a sound source for the presence of a particular tone. The algorithm is simpler than an FFT and therefore a candidate for small … Continue reading

An Orchestra of Bits and Bytes: Time-Triggered Advanced Driver Assistance Systems

Multi-sensor object tracking is an important feature for advanced driver assistance systems in future automobiles. Most state-of-the-art systems cannot guarantee deterministic processing of the sensor values due to unsynchronized sensing and processing units. To overcome this shortcoming we propose a … Continue reading
