Design and implementation of SOPC partial reconfigurable Dual-core flight

Traditional flight control systems adopt CPU mode, which is expensive, power-consuming and limited to thermal redundancy switching. To overcome this shortcoming, a reconfigurable dual-core parallel computing flight control system based on SOPC technology is proposed, which has the characteristics of high reliability, low power consumption and miniaturization. Dual-core parallel processing is used. In order to improve the efficiency of operation and processing of flight control system, dynamic reconfigurable technology based on SOPC is used to realize cold backup and data recovery in failure mode of flight control system. In this paper, the architecture, hardware platform, reconfigurable design and hardware-software co-design method of the system are described in detail. Finally, the method of data interaction between two cores and the reconfiguration strategy are given.
