| Abstract: | Response to the difficult of dealing with mass data larger than 2GB,this paper presented a standard method of data read and write based on memory-mapped file,which is faster,more flexible and higher efficiency,etc.After putting the method into practice,as it used to read or treatment or display the mass acquisition data,the result meets demand and proves to be good. |
