The widespread use of embedded systems mandates the development of industrial software design methods, i.e. computer-aided design and engineering of embedded applications using formal models (frameworks) and standardized prefabricated components, much in the same way as in other mature areas of engineering such as mechanical engineering and electronics. These guidelines have been used to develop Component-based Design of Software for Embedded Systems (COMDES). The paper gives an overview of the COMDES framework, followed by a presentation of a generic component types, such as function blocks, activities and function units. The execution of function units is discussed in the context of a newly developed execution model, i.e. timed-multitasking, which has been extended to distributed embedded systems.

利用TL431作大功率可调稳压电源，里面有具体的电路，大家可以借鉴。-using TL431 for power adjustable power supply, inside a specific circuit, we can draw on.

当我们想在uClinux上迁移到NiosII时，需要在NiosⅡgcc交叉编译器上安装Linux。请下载RAR解压，然后只在Linux下解压安装！

本文论述了利用Linux作为嵌入式操作系统，通过内核如何保护自己的程序，以及应用程序的四个主要部分，来减小自己的体积，从而为嵌入式系统的存储设备配置内存。

Raw-OS 操作系统特性 符合MISRA C 2004 编码规范，除了几个规则之外。 采用了目前业界最先进的hybrid（混合中断架构)不仅实现了最大关中断时间为0us,cpu利用率更是远超越ucos 3等实时系统。 内核最大关中断时间无限接近0us(整个内核最大关中断时间只有20句汇编）, s3c2440系统最大关中断时间实测0.8us。 支持idle任务级别的事件驱动(协程)，基于状态机机制(fsm+hsm),所有idle 级别的事件任务共享一个栈！ 支持MPU内存保护模块 支持task 0以及workqueue的中断下半部机制，轻松降低系统最大关中断时间到最低,以及大大提高了系统的实时性。 支持task 256个优先级 支持task无限多个 支持semaphore无限多个 支持task级别的私有semaphore,即一个任务有一个私有信号量。
