摘要
基于消息驱动机制的VHDL程序设计方法,由于消息驱动机制增加了消息搜索进程和处理进程,在搜索进程中登记消息即可扩展子系统。其作法是采用每个处理进程的全局信号,通过消息搜索进程,接收其它进程、子过程或块发出的消息并调用相应处理进程以实现。程序设计实例证明,该方法能使程序更灵活,系统功能易扩展与改进。
Because the processes of message search and message processing was added in news message driving mechanism, in searching process, that news can be registered to expand subsystem with VHDL programming method based on message driving mechanism. The overall signal of each processing course is adopted, process of message search receives news is sent out from other process, sub-course or block and corresponding processing course is transferred to receives news. The programming of example it proved that this method of programming is more flexible, more easy for extending and improving system function.
