摘要

我们提倡ThingSpire OS，一个基于WebAssembly的全新物联网操作系统，用于云边缘集成。通过设计，WebAssembly被认为是ThingSpire OS中的一流公民，以实现物联网设备，边缘和云之间的一致执行。此外，ThingSpire OS通过实现基于AoT (Ahead-of-Time)编译的WebAssembly运行时，实现了WebAssembly在资源受限设备上的高效执行，占用空间小，无论模块位于何处，都能实现无缝的模块间通信，并利用了一些优化，如用于内存隔离和控制流完整性的轻量级可抢占调用。我们实现了ThingSpire操作系统的原型，并对其模块间通信性能进行了初步评估。

ThingSpire OS: a WebAssembly-based IoT operating system for cloud-edge integration

We advocate ThingSpire OS, a new IoT operating system based on WebAssembly for cloud-edge integration. By design, WebAssembly is considered as the first-class citizen in ThingSpire OS to achieve coherent execution among IoT device, edge and cloud. Furthermore, ThingSpire OS enables efficient execution of WebAssembly on resource-constrained devices by implementing a WebAssembly runtime based on Ahead-of-Time (AoT) compilation with a small footprint, achieves seamless inter-module communication wherever the modules locate, and leverages several optimizations such as lightweight preemptible invocation for memory isolation and control-flow integrity. We implement a prototype of ThingSpire OS and conduct preliminary evaluations on its inter-module communication performance.
