Chen Xiao-jing · Journal of Yangtze University · 2013
Aiming at the characteristics of cloud-to-ground lightning signals storage,the design of storage system of lightning detection based on FPGA and SDRAM is proposed.Crucial problems and the corresponding solutions in the design of SDRAM controller are introduced.Hardware circuit of SDRAM interface is introduced and the state transition diagram of time program controller which is the core of SDRAM controller is given.Lastly,the results under software SIGNALTAPII are given and they show that the design can meet the requirement of lightning detection unit.
