Abstract

This paper presented a high speed data acquisition system for real-time application. The hardware of system mainly consists of data acquisition, distribution and storage section. A 3Gsps ultra high-speed ADC is applied in acquisition section. In distribution section, the original data stream will be distributed into four streams. Each data stream will be stored into one solid-state storage card which is composed of NAND flash array. In aspect of software, implementation methods of DDR3-based FIFO and NAND flash controller were introduced in detail. System evaluation results show that system achieved high bandwidth (up to 3.0GB/S) and good SNR (up to 45dB).
