基于IP核复用技术的CAN总线SOPC设计

摘要

The design scheme af the CAN bus SOPC based on lP core duplicate technology was pmposed.A design framework of CAN controller lP core was introduced, and a complete CAN bus system was implemented using the Cyclone Ⅲ type fPGA chip,which had a set of 51 SCM lP core.memory lP core.CAN controller IP core and necessary embedded software.Finally, both the software simulation and hardware tests verify the correctness of this CAN bus system.%提出了一种基于IP核复用技术的CAN总线SOPC的设计方案.介绍了CAN总线控制器IP核的设计架构,并在CycloneⅢ型FPGA芯片上实现了一个集8051单片机核、存储器核、CAN控制器IP核以及嵌入式软件为一体的完整CAN总线系统,通过软件仿真和硬件测试都表明该系统性能良好.
