| Abstract: | The ethernet digital image telemetry encoder has the problems of various function,complicated structure,required high real-time.We use the combination hardware platforms of high-performance microcontroller and FPGA（Field-Programmable Gate Array）to receive ethernet digital image data.The PCM（Pulse Code Modulation） frame format can be programmable and meet the standard of telemetry IRIG106（Inter Range Instrumentation Group 106）,configuring and transforming IRIG-B time code.The dispatch and management are of high-speed and efficiency.The designing and making of hardware circuit about Multi-level signal output validated the accuracy and reliability of hardware circuit by the environment of laboratory and user site test. |
