The Research of High-speed Data Storage Technique in PXI-bus Parallel Preprocessing Dynamic Data Acquisition System

摘要

The data storage rate has been the one of the bottleneck of the whole data acquisition system’s rate. In the development of the “PXI-Bus Parallel Preprocessing Dynamic Data Acquisition System”, the problem has been settled by this way: first, the continue physical memory should be allocated in the host computer, and the data acquisition cards send the data to this part of the memory, then the host computer read the data from the memory for real time show and real time storage.
