摘要
It discloses a technical solution of the present disclosure partitions a high-speed data code stream into a plurality of sequentially arranged data blocks so as to write the data blocks sequentially to a circular cache. The circular cache is comprised of N cache segments that share a write pointer, each cache segment owning an independent read pointer. The data blocks are sequentially written into the N cache segments; data will be continuously written to the 1st cache segment; data will be read from the cache segment at a relatively low rate and written to a corresponding SD card, thereby implementing data speed reduction; a controller will integrate the disordered data into a same SD card following the original arrangement order, thereby completing all data storage work.
