| Abstract: | According to the fact that the current design of micro-spectrometer needs to replace CCD,PDA device frequently,using Cypress＇s AD2131Q and Cyclone series FPGA design a universal acquisition system which can be applied to a variety of linear array CCD and small area array CCD,the design of 16In8Out asynchronous FIFO provides 192Kb cache.EZ-USB adopts special fast bulk transfer mode,which greatly improves the speed of data transmission.The system achieves a variety of linear array CCD collection and correlated double sampling （CDS）technique,it features speediness, convenience and modularization. |
