| Abstract: | This paper introduces the study and implementation of real-time capturing and displaying system for electronic endoscope.AMCC S5933,a special PCI controller,is utilized to implement PCI bus interface,and an FPGA is used as the kernel module to control the data transferring and related chips working.As to the software,a device driver of PCI image capturing card for Windows with WinDriver is developed,which performs the data transferring from PCI bus to the host memory in DMA mode of S5933 directly.An application with DirectDraw components is developed to access display hardware directly leading to display in real-time.Finally experiment results are present and these results show that this system is of good performance.and operates very well. |
