Software Design Of Medical Electronic Endoscope Application System Based On Tilera

Currently, endoscopic has become one of the essential equipment in medical examination. Video Resolution and image quality directly affects the use effect of the endoscope, it also marks the development level of endoscopic techniques. The traditional endoscope video solutions based on DSP can’t encode and decode efficiency at the same time. The research of high-definition endoscopic application system has important significance.In this paper, we design the software of medical electronic endoscope application system based on Tilera platform, it can be divided into control board and codec boards, the real-time video is1080p(60fps), it implements the collection and display, real-time processing, codec management etc. Using PCI Express and DMA technology, it implements the high speed data communication between FPGA and control board, control board and codec board. It also use multi-thread parallel programming and UNIX Socket technology to implement the system function. We also implement the codec function based on the H.264codec interface, JPEG-XR codec interface. After the function test:each system function is working correctly, the bandwidth of real-time video is about480MB/s, the codec bandwidth is about480MB/s, codec performance meet the needs of system requirements, it can encode and decode at the same time, it’s quality conforms to the H.264High Profile standards.
