Performance Measurements of the Multimedia Testbed on Mach 3.0: Experience Writing Real-Time Device Drivers, Servers, and Applications

Abstract

Multimedia has generated a widespread interest in real-time support within general purpose operating systems. In addition to real-time support, multimedia often requires large amounts of data to be moved between devices and processes. The Multimedia Testbed is a set of applications that stress consistent low-latency response and efficient interprocess communication for large blocks of data. The Multimedia Testbed was ported to the Mach 3.0 Operating System where performance was measured. Experiments were conducted to compare various techniques for IPC and disk reads. Experience with fixed priority scheduling, user-level device drivers, and a high-resolution timer are also reported. Performance measurements, Multimedia, Real time, Operating systems, Interprocess communication.
