SRAM-based FPGAs have been widely used in space engineering. However, the configuration memory in SRAM-based FPGA is susceptible to the single event effects (SEE). It can disrupt the communication or control functions of the spacecraft. To mitigate SEE effects of the SRAM-based FPGAs used in space radiation environment, Beijing Microelectronics Technology(More)
The compound eyes of insect are highly optimized for the task of visual acquisition of relevant information from the environment, such as moving object detection. These have attracted the attention of many researchers in recent years. The advantages of compound eyes are illustrated in this paper in relation to other approaches in moving object detection.(More)
