High–Speed Data Acquisition System Based on ARM & Linear-CCD
This paper presents a high speed acquisition system of linear-CCD based on ARM, high-speed linear-CCD and high-speed ADC are selected. As the sampling speed of A/D is slower than the working clock frequency of ARM, CPLD and FIFO are used as I/O between A/D and ARM. It makes the circuit works harmonious, simple and easy controlling, and also increases the efficiency of ARM. In order to increase the communication speed, the Universal Serial Bus (USB) technology is adopted to communicate with the PC. ARM is the key processor utilized to control the data sampling, data compute and data transfer. As a result, the whole system works effective. The system can be applied to the high speed data acquisition and operation situations from multi-channel analog signals.
