DATA WRITING, CONSISTENCY CHECKING AND READING METHOD AND APPARATUS

摘要

A data writing, consistency checking and reading method and apparatus. By writing multiple data blocks reorganized based on a time stamp to a storage medium in parallel by means of multiple channels in sequentially cyclic order block by block, on the one hand, compared with the page-by-page writing in the prior art, multiple blocks in a memory can age evenly, thereby improving the service life of the memory; on the other hand, parallelization can be implemented to a greater extent, and the stability of data writing can be improved. In addition, the use of the time stamp and block data index information can improve the speed and stability of data reading, and particularly can improve the use efficiency of a solid state disk, thereby better meeting the application requirements of autonomous driving scenarios.
