| Abstract: | A system architecture design and implement methodology about the high speed infrared image sampling system based on USB 2.0 is presented. Through using CPLD to implement the timing control and drive circuits of the IRFPA sonde and the FIFO and to merge odd and even data sampled from the sonde and using FIFO to be data cache, a point to simplify the system architecture and optimize the system performance is carried and a set of IRFPA high speed image sampling system is build up. The result of experiments indicates that the system can satisfy the request to use, and the design idea is useful for reference to other similar system. |
