A design model of NC code complier based on ANother Tool for Language Recognition ( ANTLR ) was presented, which adopted the Extended Backus Naur Form(BNF) ( EBNF ) to define the NC program syntax rule. 采用了扩展的巴科斯范式(EBNF)定义NC程序语法规则,提出了一种基于语言识别工具(ANTLR)的NC代码编译器的设计模型。
Two technologies are used in this method : high speed parallel string match based on pipeline and high speed message ( validity ) check based on ABNF ( Augmented Backus Naur Form(BNF) ). 这种方法采用基于流水线的高速并行字符串匹配结构和基于ABNF(AugmentedBackusNaurForm)范式定义的高速域值合法性检查。
