基于CPLD的智能看门狗设计与实现

摘要

智能看门狗是基于CPLD 技术，使用VHDL 语言实现的，具有功能灵活可变、参数设置方便、使用简单快捷等优点。由于C PLD 具有可反复擦写/编程特性，为看门狗的设计和调试提供方便。%IntellectivewatchdogisrelizedbyVHDL languageandbasesonCPLD technologywhichhasover-riding advantages of flexible and variable function ,sim ple and convenient param eter setting.It is m ore convenient to design and debug the intellective dog w ith the specificity of reversalerasing and program m ing.
