摘要
介绍了俄罗斯军用标准ΓОСТ18977和PTM1495。重点进行了IP核总体设计,收发通道和CPU接口的详细设计,通过设置控制、状态等多功能寄存器实现各通道独立工作,软件设计采用状态机保证了协议通信的正确性,并在QuartusⅡ5.0集成开发环境下予以实现。经验证用本方法设计的IP核能很好地实现8通道同时收发的功能,且各个通道能独立设置通信频率、奇偶校验等,解决了以往该类芯片通道少、功能单一的缺点。
Russia military standard FOCT18977 and PTM1495 are introduced. The structure of IP core and design of sending channel, receiving channel and CPU interface are introduced. By setting of multi - function registers, such as control and status registers, each channel may work independently. State - ma- chine program is used to ensure accurate communication,and the application is designed with QuartusH5.0 IDE. The results of test show that this IP core can satisfy 8 Rx and 8 Tx channels at the same time, each channel can set communication frequency and parity check etc independently. Thus the disadvantages of such chips are overcome.
