Design of Data Acquisition System Based on Linear Array of CCD and Its VHDL Implementation

In this paper,we introduce a new realization method in design of data gathering system which uses VHDL(one kind of standard hardware description language) to compile the drive program.According to the new design method,the block diagram of the new data acquisition system is presented,and the design of CPLD device is discussed.Finally,simulated verification is made using VHDL language and the software of QuartusⅡ.Results show that the new method can simplify the design ,reduce cost and has good practical usability.
