【摘要】：为实现相控阵天线波控系统小型化、芯片化的目的,设计了一种基于Avalon总线的CAN控制器IP核。参照CAN2.0B协议规范,给出了CAN控制器IP核的功能结构,利用Verilog硬件描述语言完成了控制器接口逻辑、位流处理器、位时序逻辑等模块设计,并进行了设备驱动及应用软件开发。将设计的CAN控制器IP核、Nios II微处理器、多个单元相位控制器IP核等集成到FPGA中构成子阵级波束控制的SoPC系统。最后对CAN总线的通信性能进行了实验测试。结果表明:设计的CAN控制器IP核能够在实际CAN网络中稳定可靠地收发数据。基于这种方式构建的系统,扩展方便、可移植性高、具有较强的适应性,也可用于高密度、紧凑型工业控制领域。
[Abstract]:In order to realize the miniaturization and chip of phased array antenna wave control system, a CAN controller IP core based on Avalon bus is designed. According to the CAN2.0B protocol specification, the function structure of IP core of CAN controller is given. The controller interface logic, bit stream processor, bit timing logic and other modules are designed by using Verilog hardware description language, and the device driver and application software are developed. The designed CAN controller IP core nios II microprocessor and several cell phase controllers IP cores are integrated into FPGA to form a sub-array beam control SoPC system. Finally, the communication performance of CAN bus is tested experimentally. The results show that the IP core of the designed CAN controller can send and receive data stably and reliably in the real CAN network. The system based on this method has the advantages of convenient expansion, high portability, strong adaptability, and can also be used in the field of high-density, compact industrial control.
