Pebble: a component-based operating system for embedded applications
John L. Bruno, José Carlos Brustoloni, Eran Gabber, Avi Silberschatz, Christopher Small · 1999
The Pebble operating system is intended to support complex embedded applications. This is accomplished through two key features: (1) safe extensibility, so that the system can be constructed from untrusted components and reconfigured while running, and (2) low interrupt latency, which ensures that the system can react quickly to external events. In this paper we discuss Pebble's architecture and the underlying technology used by Pebble, and include microbenchmark performance results on three MIPS target systems. The performance measurements demonstrate that Pebble is a good platform for complex embedded applications.
