【摘要】 该文设计并实现了一种基于乒乓操作的高速数据采集系统。该系统使用两片SDRAM,同时设计了一种全新的SDRAM控制器,以现场可编程逻辑门阵列作为核心平台,通过高速数据接口,将采集到的数据通过总线传输到处理模块进行后续处理,从而完成数据的采集和处理任务。通过FPGA软硬件平台验证表明,该系统各模块均工作正常,并达到吞吐率指标,可满足数据采集、数据缓冲和数据接口匹配的需求。更多还原

【Abstract】 One high-speed data acquisition system based on table tennis opera-tion has been desig ned.This system use two SDRAM chips with a new SDRAM contr-oller,use Field Programmable Gate Array(FPGA) as a key design platform of the whole system,use to build table tennis opera tion module,and then let the data collected transmit to the next processing modules,through a v ariety of high-speed data interface or bus,so as to complete the data acquisition and proce-ssing tasks.Some experiments and tests based on FPGA show each module in this system works well,and meets the throughput rate requirement,and has achieved the data acquisition,data buffering an d data interface matching requirement.更多还原
