Abstract:
A solution of embedded endoscope video processing system based on TILE-Gx multicore processor is designed. The system supports 2-channel input and output port for 1080p60 HD video data and real-time H. 264encoding /decoding of YCbCr422 format video. FPGA is applied to realize the input / output port of video data. 4 pieces of TILE-Gxprocessors are applied to encode / decode,another TILE-Gx processor is applied to the system management,video mixing, and hard disk storage. Experimental results show that,the performance of encoding and decoding fulfills the requirement of high definition and real-time of endoscope,and the image quality reaches H. 264 High Profile level.
