地震勘探中实时数据处理系统的设计与实现
Design and Realization of Real-time Processing System for Seismic Exploration
【摘要】 针对地震勘探实时数据处理,设计了一套基于FPGA和ARM的高速大容量数据实时处理系统。系统充分利用了多处理器架构的优势,实现了高速数据的接收、大容量数据的存储、协议解析、数据拼接、时序转道序和无死时间乒乓存储功能,同时利用了嵌入式Linux操作系统保证了灵活性和可靠性。
【Abstract】 For solving real-time seismic data processing problems,a high-speed,large-capacity and real-time data processing system is designed based on FPGA and ARM.With the advantages of multi-processor,DRPS has the characteristics of high-speed data receiving,large-capacity data storage,protocol analysis,data splicing,data converting from time sequence into channel sequence,no dead time data ping-pong storage,etc.And with the embedded Linux operating system,DRPS has the characteristics of flexibility and reliability.
