This paper introduces the memory-mapped method of the data exchange between the CAN communication card and PC,and gives the realization of dual-port SRAMs based on XC9500 series in the CAN communication card,including the circuit and the VHDL program.
介绍了实现CAN通讯卡和PC机的数据交换的内存映像法;用Xilinx公司XC9500系列CPLD芯片,实现CAN通讯卡中双口RAM的控制电路和VHDL程序。
