A Low-power High-efficient Garbage Collector for Embedded Java Systems

摘要：0219870 PI：Morris ChangIowa StateThe thesis of this project is very simple：垃圾收集的性能对于成功部署分布式Java嵌入式系统至关重要。与为桌面或服务器环境编写的应用程序相比，此类系统的应用程序具有不同的操作要求。它们包括频繁的软件更新、低功耗、低资源可用性、分布式计算能力和实时操作约束。因此，这些设备的垃圾收集器必须设计为支持这些要求。垃圾收集（GC），或自动动态内存管理，是Java中许多有吸引力的特性之一。它允许程序员更有效率，软件更健壮。另一方面，由于频繁的内存访问，它也因侵入性和消耗大量功率而臭名昭著。因此，垃圾收集会严重降低性能，影响Java嵌入式设备的生存能力。

Abstract:0219870PI: Morris ChangIowa StateThe thesis of this project is very simple: the performance of garbage collection is critical to the successful deployment of distributed Java embedded systems. Applications for such systems have different operating requirements than applications written for desktop or server environments. They include frequent software update, low power consumption, low resource availability, distributed computing capability, and real-time operating constraints. Therefore, garbage collectors for such devices must be designed to support those requirements. Garbage Collection (GC), or automatic dynamic memory management, is one of the many attractive features available in Java. It allows programmer to be more productive and software to be more robust. On the other hand, it is also notorious for being intrusive and consuming large amount of power due to frequent memory accesses. As a result, the garbage collection can severely degrade the performance and affect the viability of Java embedded devices.
