Embodiment Construction

[0012] Please refer to image 3 , which is a generalized flowchart of an embodiment of the data access method of the present invention. Broadly speaking, the data access method of the present invention includes step 310 and step 320 . Wherein, in step 310, the data access method of the present invention will receive multiple access requests issued by the operating system and corresponding multiple memory addresses, so as to perform multiple data storage on the storage unit (such as flash memory). fetch operation, and the multiple data access operations will respectively correspond to the multiple memory addresses associated with the multiple access requests. Next, in step 320, the data access method of the present invention will judge the consistency of the data read and write directions of the multiple access requests issued by the operating system and the continuity of the multiple memory addresses, so as to perform the operation on the storage unit. A pre-guessed access o...

Abstract

The invention provides a data access method and a related control system, which improves the reading and writing performance of the data storage unit by pre-accessing the data storage unit. The data access method of the present invention includes: receiving multiple access requests and corresponding multiple memory addresses to access a storage unit multiple pieces of data corresponding to the multiple access requests; and according to the multiple access requests The consistency of the requested data reading and writing directions and the continuity of the plurality of memory addresses enable a pre-guessed access operation to the storage unit.

Description

technical field [0001] The present invention relates to data access, in particular to a data access method and a related control system for improving data access efficiency through pre-guessing access means. Background technique [0002] Generally speaking, the relationship between the operating system / high-level application program and the hardware device (for example: the control circuit in the storage device) can be referred to figure 1 . Wherein, the operating system 110 interacts with the control circuit 130 through a driver program (or control firmware) 120 , such as: using the control circuit 130 to access data from a storage device (not shown). In the known technology, the detailed flowchart of the data access process can be further referred to figure 2 . as the picture shows, figure 2 The flow chart of shows the steps involved in two consecutive data access operations. First, in step 201, the operating system / high-level application program will send an access...
