Embodiment Construction

[0014] The present invention will be further described below in conjunction with specific embodiments.

[0015] In fact, the method of the present invention is more concise and effective, from figure 2 and image 3 It can be seen from the figure that the present invention first defines the drive interface of the flash memory chip. Through this step, all operations on the flash memory chip will call this interface. This drive interface is the interface that the application part will use when operating the flash memory chip. Here The interface will determine which driver should be used to drive the chip. Then the driver and the driver interface of the flash memory chip are stored in a specific storage space. Since the application part of the system will perform operations on the flash memory chip, the system must have the driver of the flash memory chip. The present invention combines the driver of the chip and the driver interface Stored in a specific storage space of the sy...

Abstract

The method includes following steps: (1) defining driving interface of flash chip; (2) storing program and interface for driving flash chip into specific space; (3) assigning mode of application part for operating flash chip. The invention has advantages of good transplant performance, expandability and independence. When type of flash chip is changed, the invented method adds (or replaces) new driving program to specific storage space without need of binding application with flash chip.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method for driving a flash memory chip by an embedded system. Background technique [0002] With the development of technology and the increasing demand for computer systems in various fields of society, the intelligence of embedded systems is also gradually improving. Existing embedded systems often have some simple management and configuration functions. Functions are generally completed by relevant control information stored in the system, and embedded systems usually use storage media such as flash memory chips to store these information. Considering the convenience of use, flexibility, cost, etc., the flash memory chips selected in the embedded system often have multiple manufacturers and types, so the embedded system needs to provide drivers for operating these flash memory chips. Existing practices such as figure 1 As shown, the hardware driver and the application software of ...
