学生成绩管理工作是学校学生管理工作的重要组成部分，现在相当一部分学校的学生成绩管理工作仍沿用手工方式。随着学校规模的扩大、学生人数的增加，效率低下、容易出错的手工方式越来越不适应实际管理工作的需要，按照软件工程原理和数据库技术开发学生成绩管理系统已成为学生管理部门的迫切需要。-student performance management is the management school students an important component, considerable part of the school management of student achievement is still used manual. With the increased scale of the schools, the number of students increases, inefficient and error-prone manual increasingly unable to meet the actual needs of management, in accordance with principles of software engineering and database technology student performance management systems have become students of management an urgent need.

本文的核心linux2.6.6新特点的基础上探讨了…
本文首先分析Linux2.6.6内核新特性的基础,探讨对Linux进行实时化和嵌入式化,即通过配置内核,裁减shell和嵌入式C库对系统定制,使整个系统能够存放到容量较小的FLASH中。然后简单介绍了防火墙的概念,深入地分析了Linux2.6.6版新型内核防火墙netfilter框架的工作机制及其实现的方式。-In this paper, the kernel Linux2.6.6 the basis of new features to explore on the Linux and embedded real-time, that is by configuring the kernel, the reduction of shell and embedded C library on the system customization, so that the entire system to the capacity to store more FLASH in the small. And then briefly introduced the concept of a firewall, in-depth analysis of the new kernel version Linux2.6.6 firewall netfilter framework of the working mechanism and its implementation approach.

ST7787 chip SPEC, BYD 2.4inchLCM the SPEC. The ST7787 is a single
ST7787 芯片的SPEC，比亚迪2.4inchLCM的SPEC。The ST7787 is a single-chip controller/driver for 262K-color, graphic type TFT-LCD. It consists of 720 source line and
320 gate line driving circuits. This chip is capable of connecting directly to an external microprocessor, and accepts Serial
Peripheral Interface (SPI), 8-bits/9-bits/16-bits/18-bits parallel interface. Display data can be stored in the on-chip display
data RAM of 240x320x18 bits. It can perform display data RAM read/write operation with no external operation clock to
minimize power consumption. In addition, because of the integrated power supply circuits necessary to drive liquid crystal,
it is possible to make a display system with the fewest components.-ST7787 chip SPEC, BYD 2.4inchLCM the SPEC. The ST7787 is a single-chip controller/driver for 262K-color, graphic type TFT-LCD.
