本文介绍了在Visual Basic6.0环境下采用“自上而下地总体规划，自下而上地应用开发”的策略开发一个管理信息系统的过程。通过分析某一学校学生管理的不足，创建了一套行之有效的计算机管理学生的方案。文章介绍了学生管理信息系统的系统分析部分，包括可行性分析、业务流程分析等；系统设计部分主要介绍了系统功能设计和数据库设计及代码设计；系统实现部分说明了几个主要模块的算法， 本系统界面友好，操作简单，比较实用。-This paper describes the environment in Visual Basic 6.0 adoption of the "top down overall planning, Application to the development of bottom-up "strategy to develop a management information system process. By analyzing a school student management deficiencies, create a set of effective management of student computer programs. This paper introduces the student management information system analysis, including feasibility analysis, business process analysis; system design some of the major functions of the system design and database design and code design; System explains some of the major modules of the algorithm, the system friendly interface, simple operation, more practical.

In a preemptive priority based RTOS, priority inversion problem is among the major sources of deadline violations. Priority inheritance protocol is one of the approaches to reduce priority inversion. Unfortunately, RTOS like uC/OS can’t support priority inheritance protocol since it does not allow kernel to have multiple tasks at the same priority. Although it has different ways to avoid priority inversion such as priority ceiling protocol, developers still have some difficulties in programming real time applications with it. In this paper, we redesign the uC/OS kernel to provide the ability to support round robin scheduling and implement priority inheritance semaphore on the modified kernel. As result, we port new kernel with priority inheritance semaphore to evaluation board, and evaluate the execution time of each of the kernel service as well as verify the operations of our implementation.-In a preemptive priority based RTOS, priority inversionproble
