Keynote: When Wasm Meets Cyber-Physical Systems: A Discussion of WebAssembly in Real-Time, Safety-Critical Systems – Emily Ruppel, Research Scientist, Robert Bosch LLC

Programming applications for real-time, safety critical systems is challenging. These systems are composed of an initial layer of heterogeneous devices, where each is directly connected to sensors and actuators, and then networked to external compute resources, like edge or cloud servers. The whole system operates under tight deadlines, and complexity explodes. Further, traditional techniques for managing complexity in distributed systems are too resource intensive and cannot meet real-time guarantees. In contrast, WebAssembly’s low overhead and easily embeddable design make it a promising choice for lightweight virtualization in resource constrained systems. In this talk we will discuss our ongoing work applying WebAssembly to safety-critical systems in the industrial automation and automotive domains. We will detail opportunities that WebAssembly provides for decoupling applications from hardware and describe several of the challenges with using Wasm in deeply embedded settings.
