RTC-Threads: A User-Level Real-Time Threads Package for Multimedia Systems
Summary :
In forthcoming multimedia environments, continuous-media data, such as video and audio data, will be used by a variety of multimedia applications. Multimedia applications require efficient and flexible support from real-time operating systems. This is because the changes in system and network loads require dynamic management of real-time thread behavior. If threads are implemented at the user level, operations on threads can be processed at the user level, and the efficient management of threads becomes possible by avoiding kernel interventions. Thus, we can provide an effective platform for multimedia applications. The goal of our work is to realize high-performance user-level real-time threads which satisfy the above requirements of multimedia systems. In this paper we describe the design and implementation of a user-level real-time threads package, called RTC-Threads, which is being developed on the RT-Mach microkernel. The results of performance evaluations show that our user-level real-time threads outperform real-time kernel-provided threads, which are implemented in the microkernel, in terms of efficiency and accuracy.
