Towards an Analysis of Garbage Collection Techniques for Embedded Real-Time Java Systems

From a real-time perspective, the garbage collector (GC) introduces unpredictable pauses that are not tolerated by real-time tasks. Real-time collectors eliminate this problem but introduce a high overhead. Another approach is to use memory regions (MR) within which allocation and deallocation are customized. This facility is supported by the memory model of the real-time specification for Java (RTSJ). This paper provides an indepth analytical investigation of the problems and solutions of Java garbage collection techniques regarding it use in embedded real-time systems
