| Abstract: | This paper presents a real time image capturing and displaying system for medical electronic endoscope based on PCI bus using AMCC S5933 as the PCI controller and FPGA as the transferring controller. The theory of system realization, hardware structure, software design and FPGA design for transferring control of the system are mainly discussed. The image capturing frequency of the system can reach 33MHz. It resolves real time transferring and storing of image data effectively and provides convenience for real time image signal processing for medical electronic endoscope. |
