【摘要】 利用SOPC技术,将8051 IP核与CAN IP核有机融合,提出了一种创新型的控制器局域网(CAN)节点设计方案。介绍了如何使用硬件描述语言(HDL)实例化8051 IP核和CAN IP核,描述了这两个软核的接口类型及它们之间的握手细节。编写测试程序,综合整个工程,并将生成的工程代码下载至FPGA运行。结果表明:使用SOPC技术设计的CAN节点通信良好,利用可重配置的IP核技术,可以实现更加复杂的功能,系统的设计也会更加灵活、稳定、可靠。更多还原

【Abstract】 SOPC technique is used to organize them and demonstrate the combination of CAN(Controller Area Network) IP Core and 8051 IP Core.Then this paper proposes an innovative approach to design the CAN node,introduces the use of the Hardware Description Language(HDL) for implementing 8051 IP Core and CAN IP Core,describes the interface type of these two soft-core and the details of the handshake between them makes a test procedure,integrates the whole project and sends the object code to FPGA.The results indicate that the CAN node which is designed to use the SOPC technology is perfect in the communication,and with the help of reconfigurable IP core technology,multiple functionalities can be realized and the design of this system is of more flexibility,stability and reliability.更多还原
