Abstract
This paper presents how the modular architecture used for the CHORUS/MiX V.3.2 system enables system writers to encapsulate UNIX Ò device drivers within UNIX processes, and the possibilities offered by this feature. The CHORUS Ò architecture is designed to support a new generation of open and distributed operating systems. A microkernel provides generic services allowing servers that cooperate within subsystems to offer standard interfaces: a UNIX SVR3.2 interface is available and a UNIX SVR4 interface is under development. The CHORUS microkernel provides services to manipulate actors and threads (memory management, scheduling... ). It also offers a distributed Inter-Process Communication (IPC) facility and services to dynamically connect user provided functions to hardware interrupts and traps. CHORUS/MiX V.3.2 is implemented as a set of the following servers: a Process Manager, a File Manager, a Terminal Manager and a Socket Manager (to provide BSD sockets). In addition to standard ...
