Abstract

Abstract

In order to modify the disaccord of output sequency of a double-tap Charge Coupled Device(CCD), an improved design method for software RAM is proposed, and the output of CCD is conformed by this method. Firstly, a dual-port RAM is constructed by using Block RAM of Xilinx Virtex series Field Programmable Gate Array(FPGA). Since the sequence of data from tap1 is the same as that to be conformed before, this paper comes up with an improved method based on the traditional Ping-Pang operation to conform the output data from the CCD. Comparing to the traditional Ping-Pang method, the resource consumption of designed software is greatly reduced by 25%. It is proved to be valid and accurate by the simulation result of ModelSim. The new method which has been applied in the project successfully can save hardware resources and reduce the hardware cost greatly.
