Method and device for storing and reading data in embedded system
2007
The present invention provides a method of storage and data reading in an embedded system, resolving the problems of chip storaging and checking performances and lower use lift in the embedded system; when storaging data, the opening storage data and its valid record number, erasing frequency and size of each record are acquired, the sector numbers provided by embedded chip are determined according to the valid recording numbers and the erasing frequency respectively, and the storage space is distributed in the embedded chio according to the maximal sector numbers, and the data is stored in the storage space and records storage position in the data tracing structure list; when reading data, the position in the embedded chip of the data storage corresponding to the data name is determined by tracing data tracing structure list recorded by data, and the data is read in the storage position of the embeddd chip; the method of the invention greatly enhances storage and checking performances of the embedded chip.
