摘　　要：软件调试支持是操作系统的重要组成部分,而由于内存管理不善造成的软件BUG占软件故障的很大比例。从内存管理的角度,讨论了Elastos操作系统对软件调试的支持。介绍了Elastos的内存布局和堆管理器算法,然后论述了堆、栈的内存管理,以及针对软件调试所提供的栈保护页设置、堆块前/后内存越界检查等。最后简要地介绍了构件Domain技术和基于伪驱动的内核窥探调试。通过Elastos内存管理的调试支持,可以提高修复和内存管理相关的BUG,增强软件的可靠性,减小软件的开发成本。Software debugging support is an important part of the operation system, and software bugs, due to poor memory management, accounted for a large proportion of software fault. Argues the support of Elastos operating system for software debugging in the memory management. First, it describes the virtual memory layout and Elastos heap memory management algorithm, and then discusses the heap, stack memory management, as well as some debugging surpports, such as setting up fence page in stack, cross- border checks before/after stack chunks. Finally, it gives a brief introduction of the oomponent Domain technology and debugging of kermel spy based on pseudo - driver. With the support of Elastos debug memory management,enhance the capacity of fixing the bug related to menmory management, improve the reliability of software and reduce software development costs.
