Abstract: In embedded systems, it is needed to analyze what kind of garbage collection strategy can adapt to the embedded system and content with the stability and performance. This paper analyzes the characteristics of garbage collector which the KVM uses, garbage collection algorithm which it adopts, finds the shortcoming and fallback, and brings forward ways and means to improve its garbage collector, and implements the generation algorithm based on the mark-sweep-compact algorithm.
