首先讨论了高级语言描述到硬件描述语言的映射，提出了算法到算法状态机抽象的规律；然后，介绍了现有的基本图形生成算法，包括直线的自适应算法、三角形边相关扫描算法，宽直线线刷子算法及改进的圆形、椭圆的生成算法，同时讨论了加速算法的研究现状；接下来具体讨论了基本图形的硬件实现，给出了各算法的状态机流程图、接口定义和实现框架，并且从理论角度给出了二次曲线加速算法的证明；最后采用EDA工具对VHDL程序进行仿真、综合并实现。

They require a whole recompile of all applications that use the Interface or, if that's not possible, require you to write a whole new Interface.

所有程序中用到的节点需要全部再编译，或如果这是不可能，要求你鞋整个新的接口。

For the characteristics of voile cleaning machine in textile producing, a new control system based on CAN fieldbus is presented in this paper, The principle of the system is introduced, The interface of the network and the communication protocol of the system are discussed in detail, The design of control software is also analyzed, the main program of communication is given. For CAN network communication of master and slave station,the system works reliably, and the voile cleaning is controlled intelligently. It is an advanced control technology. which is verified in practice .

针对纺织生产过程中清纱机的工作特点，提出了一种基于CAN总线技术的控制系统设计方法，分析了系统的工作原理、网络拓扑结构及其硬件构成，详细阐述了CAN总线的网络接口方法和系统通信协议，讨论了控制软件的设计，给出了CAN网络的主要通信程序，由于这种系统的主、从站之间采用CAN网络通信，实现了对清纱工程的智能控制，系统具有运行可靠、性能价格比高的特点，实践证明这是一种先进的控制技术，具有较大的推广意义。
