嵌入式Windows NT 4.0在在线TOC分析仪开发中的应用

PC10 4是测控领域常用的嵌入式硬件平台。在使用其作为在线 TOC分析仪的控制单元时 ,关键问题是选择一个适合的操作系统。根据在线 TOC分析仪的特点 ,操作系统应具备支持 X86系列处理器、支持多任务、支持 TCP/ IP网络协议、实时性要求不高的特点。在PC10 4支持的 Microsoft族的操作系统中 ,嵌入式 Windows NT 4.0和 Windows CE都满足上述条件。 Windows CE是针对手持设备而设计 ,而嵌入式 Windows NT4.0是从 Win-dows NT4.0削减得到的 ,支持完整的 API,更加适合在线 TOC分析仪的设计。目标设计器和组件设计器是嵌入式 Windows NT 4.0的两个生成工具。它们是以模块化的方式削减 Windows NT4.0的内核 ,得到自定义的嵌入式 Windows NT4.0。在嵌入式Windows NT 4.0上进行应用软件开发 ,与通用软件开发的区别不大 ,从而可以加速产品市场化的速度。

Application of Windows NT 4.0 embedded in the development of process TOC analyzer

PC104 is a general embedded hardware platform in the measurement and control field. During the use of the control unit of the process TOC analyzer, the selecting of a suitable operating system is the key. According to the characteristics of the process TOC analyzer, the operating system should be able to satisfy the essential requirements such as supporting X86 series processors, supporting multi|assignment, supporting TCP/IP protocol, and low request on real|time. In the Microsoft family, systems supported by PC104, such as Windows NT 4.0 embedded and Windows CE can both satisfy all the above conditions. The design of Windows CE is directed to handset device, while Windows NT 4.0 embedded is obtained from decreasing Windows NT 4.0 capable supporting complete API and being more suitable to the design of the process TOC analyzer.The Target Designer and the Component Designer are two development tools of Windows NT 4.0 embedded. They decrease the kernel of Windows NT 4.0 by modularization, to obtained a customized embedded run|time image. The development of applicant software is not far different from the that of general software. So we can quicken the marketing step.
