Embodiment Construction

[0017] Such as figure 1 Shown is a schematic diagram of the application environment of the sequential access detection system of the present invention. In this embodiment, the sequential access detection system 20 (hereinafter referred to as "system 20") operates in an electronic device 2 to detect whether the access file corresponding to the access unit to be accessed is sequential access files (i.e. continuous IO files). The electronic device 2 also includes a storage device 21 , a display device 22 , and a processor 23 connected through signal lines and data lines. It can be understood that the electronic device 2 should further include other necessary components, such as batteries. The storage device 21 further includes a storage type flash memory (NAND flash) 210 .

[0018] Before the access file is accessed, the access file is divided into multiple fragments (that is, access units), and then these access units are numbered sequentially. When accessing an access unit ...

Abstract

The invention relates to a sequential access monitoring system and method. The method includes the steps that when a storage type quick flashing memory magnetic disk NAND flash terminal receives an access unit of a certain access file, whether the access file corresponding to the access unit is a continuous access unit or not is judged; if the access file corresponding to the access unit is the continuous access unit, a sequential access sign corresponding to the access file is marked to be a sign of a sequential access task. By means of the sequential access monitoring system and method, the number of write-in times of NAND flash sectors can be decreased, and time and space needed for a large amount of sequential statistics can be saved.

Description

technical field [0001] The invention relates to the technical field of data access, in particular to a sequential access detection system and method. Background technique [0002] In computer systems, disk IO management is the key to system performance. On the emerging storage type flash memory disk (NAND flash disk), due to its high-speed read and write speed, it can significantly improve the performance of the computer system, so it has begun to be valued by the database system. However, although the read and write efficiency of NAND flash for random access is much higher than that of disk, its read efficiency for sequential access can be equaled by the Redundant Array of Independent Disk (RAID) system with multiple hard disks . In order to save the precious limit on the number of write times of NAND flash, thereby increasing its service life and reducing the construction cost, there is currently an algorithm that can detect whether the access is continuous access by rec...
