Design of Man-Machine Interaction Systems Based on LCD Screen of SOPC

In order to satisfy the requirements of more and more complex man-machine interface,one touched display GUI system based on SOPC technique is designed by using FPGA device.The LCD screen and touchpad is driven by FPGA device in this system.The GUI graphic interface module is run by build-in SOPC soft core processor.The method only brings the interface image needed into the FLASH memory.And next using a serial port connects to the host MCU,which has the advantages of simple development,elegant interface and excellent applicability,comparing with disadvantages traditional method with long-time design and poor universality.
