.1.5 Gsps High-speed Signal Acquisition And Storage System Design

Digital signal processing technology is widely applied in all aspects of the field of science and engineering. And data acquisition is the first necessary condition in digital signal processing. This means that data acquisition system is an important component in the digital signal processing. With the rapid development of the digital signal processing technology, the sampling rate and the capacity for sampled data become more and more demanding.We designed a high-speed data acquisition and storage system made up of high-speed ADC with high-precision and high-performance FPGA in this item. Using the rich timing resources and storage resources, to achieve the deceleration and storage of the sampled data.This storage system mainly includes 4 data deceleration units, 8 dual port RAM storage units, can do the deceleration to the 4 channels ADC output and the storage of the decelerated 8 channels sampled data at the same time.The fourth chapter detailed the storage system based on FPGA, and given each functional unit simulation results separately.In this project, the author involved in the hardware design of system, and completed the functional simulation and the timing simulation of the storage system in the ISE environment, also did some performance Analysis to the system.
