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

摘要：0219870PI: Morris ChangIowa state本课题的论文很简单：垃圾回收的性能是分布式Java嵌入式系统能否成功部署的关键。与为桌面或服务器环境编写的应用程序相比，用于此类系统的应用程序具有不同的操作需求。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，此类设备的垃圾收集器必须设计成支持这些需求。垃圾收集（GC），或自动动态内存管理，是Java中众多吸引人的特性之一。它使程序员更有生产力，软件更健壮。另一方面，由于频繁访问内存，它也因具有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并影响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.
