高速数据传输系统实时存储的设计实现

In the high-speed data transmission systems, real-time data storage has always been the bottleneck of the system performance. This paper discusses a method of high-speed data real-time storage. The method makes a devision of the host memory to achieve the storage requirements. System uses disk array for data storage. The algorithm split the data stream into signal of each path in accordance with the data acquisition format. Sampling signal of each path is buffed with the method of function partitioning in the host memroy, and then written to the disk array forming on the respective disk file. This method is to facilitate real-time display of the original signal data and information.
