Processing group parameters in the Real-Time Specification for Java

Abstract

The Real-Time Specification for Java (RTSJ) does not support any particular aperiodic server technology. Instead it provides processing group parameters, which allow a group of schedulable objects to be allocated a capacity and a replenishment period. However, no guidelines are given on how to use them. Furthermore, there are currently no appropriate schedulablity analysis techniques which can be used to model the full generality of the RTSJ model. This paper proposes restrictions on the use of processing group parameters and discusses the problems of producing the associated analysis techniques. © Springer-Verlag Berlin Heidelberg 2003.
