SPIN (operating system)

The SPIN operating system is a research project implemented in the computer programming language Modula-3, and is an open source project. It is designed with three goals: flexibility, safety, and performance. SPIN was developed at the University of Washington.

Official websitewww-spin.cs.washington.edu

The kernel can be extended by dynamic loading of modules which implement interfaces that represent domains. These domains are defined by Modula-3 INTERFACE. All kernel extensions are written in Modula-3 safe subset with metalanguage constructs and type safe casting system. The system also issued a special run-time extension compiler.

One set of kernel extensions provides an application programming interface (API) that emulates the Digital Unix system call interface. This allows Unix applications to run on SPIN.[3]
