F1-Tenth racing cars in the RTIS Lab directed by Zhishan Guo When I first encountered an intelligent system missing a deadline—not because of a hardware fault, but due to a poorly scheduled inference—I knew something had to change. That realization sparked a journey that led to more than a decade of research, a vibrant lab at NC State, and ultimately,…

Time-Sensitive Networking (TSN) is a set of IEEE standards designed to ensure real-time guarantees for data communication over switched Ethernet. The TSN standards offer a wide range of features, including various traffic shaping mechanisms, precise clock synchronization, and network management. A key challenge arising from this wide array of features is determining how to effectively combine and evaluate them in…

MAST Analysis Tool input/outputs and internal execution flow Real-time systems are special embedded systems that must respond to external events within a strict timeframe. They are the backbone of many critical applications, from industrial automation and automotive systems, to avionics and medical devices. In these domains, a delayed response can have serious consequences, ranging from production downtime to life-threatening situations.…

Discussions about the accuracy of Performance Monitoring Counters (PMCs) are common in forums. These hardware-implemented registers track specific events within a processor’s microarchitecture, providing metrics for performance tuning or monitoring unusual activity. However, the accuracy of these counters can be compromised by system noise, other applications, the operating system, and asynchronous hardware events, especially in complex benchmarks on Intel and…

The idea of creating machines able to reason like humans is not new and has been introduced by Alan Turing in his seminal paper ”Can Machines Think?” which gave raise to the imitation test, together with other work on computability and the premises of artificial intelligence. Today, with the increased prevalence of i) autonomy, and ii) connectivity of compute systems,…

In the domain of cyber-physical systems, linear hybrid automata have emerged as a pivotal tool for modeling and verifying complex behaviors that involve both event-driven (discrete) and time-driven (continuous) changes. This blog post highlights the significant strides made in symbolic analysis techniques, particularly in the efficiency and scalability of these methods. The concept of Hybrid Automata emerged in the early…
