| Abstract: | In certain network communication equipment with MC68360 core,Am79C940 is adopted as network interface.The interface hardware circuit between Am79C940 and MC68360 is designed,and MC68360's two IDMA channels are used to receive and transmit data respectively with Am79C940 under the interrupt control mode.By establishing interrupt service routines and buffer-list data structure,the driver program based on Nucleus operating system is also designed.Running test shows that the interface is stable and reliable,and... |
