一种多通道总线控制器设计

摘要

With the electronic warfare role in modern war,the use of simulation training method to improve the ECM capability is an important way. In order to effectively enhance the EW simulation training effect,the simulation system data transmission rate is improved,and the system hardware design is simplified,the design idea of multi-channel bus controller is put forward,FPGA as the control core of USB bus and CAN bus,according to the system timing requirements realized the bus controller logic control. Practice shows that the method has the advantages of high reliability,scalability and cost effectiveness.%随着电子对抗在现代战争中作用地位的提升，利用模拟训练手段提升电子对抗能力是一种重要途径。为了有效提升电子对抗模拟训练效果，提高模拟系统数据传输速率，同时简化系统硬件设计，提出了多通道总线控制器的设计思路，将FPGA作为USB总线与CAN总线的控制核心，根据系统时序要求实现了对总线控制器的逻辑控制。实践表明，此种设计方法具有较高的可靠性、可扩展性和效费比。
