In the process of information transformation of a certain equipment’s file recording equipment, by using the framework of FPGA + ARM and the integrated design philosophy for software and hardware, we develop an embedded processing platform, which can realize reliable realtime recording, transmission and storage of multiequipment output data. Problems such as the complexity of interface signal sequential logic, signal distortion, severe noise effect, easy data loss and online function checking are solved. Tests on real equipment and application demonstrate that the embedded system can reach design requirements.
