With the optical fiber technology used in embedded systems,the amount of communication data grows in the past years.How to move data that store in the memory to disk in a high speed and correct way becomes the bottleneck of data acquisition system.This article starts with the basic function modules which are combined with producer-consumer model,and analyzes multi-thread concurrency,direct read and write disk devices without passing through file system,asynchronous I/O and other technologies used in the system.The paper Abstracts the system model and uses mathematical methods to give a feasibility analysis for the system.Experiments show that the performance of system which adopts multi-thread concurrency method is improved with a certain extent.
