【摘要】 基于PowerPC的NC系统正逐步得到应用,但其运行性能监测工具尚未开发出来。PowerPC-NC系统硬件性能参数的获取必须解决两个主要问题:内核数据的采集,用户空间与内核空间的通信。通过对Linux环境下NC性能参数采集方法的研究,提出了一种基于LKM技术的虚拟设备驱动程序方法,并在此基础上实现了PowerPC-NC系统的数据采集模块。实验结果表明,该方法具有效率高、易用性好的特点。更多还原

【Abstract】 PowerPC-based NC systems are gradually put into action, but the corresponding tools of runtime performance monitoring for these NCsare not yet developed. Two problems must be resolved for the collection of PowerPC-NC system runtime performance parameters: one is thecollecting kernel data and the other is communication between user space and kernel space. Performance parameter collecting methods in Linux areresearched and the virtual-device-driver method based on LKM is proposed. Based on this collecting method a data collection module ofPowerPC-NC system is designed and implemented, which can collect the performance parameters of NC server. Experiment results indicate that thistool has a high effectiveness and is easy to be used.更多还原
