Embodiment Construction

[0019] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0020] First, refer to figure 1 A prior art Hybrid computer system and a Hybrid computer system using a multi-port storage device are described.

[0021] figure 1 It is a block diagram illustrating a comparison between a prior art Hybrid computer system and a Hybrid computer system using a multi-port storage device. figure 1 On the left is a hybrid computer system 200 of the prior art. The Hybrid computer system 200 includes a processing unit X86201 of the X86 system and a processing unit ARM 202 of the ARM system. The X86 201 accesses the SSD 205 as its own storage area via the SATA interface 203 , and the ARM 202 accesses the flash memory 206 as its own storage area via the SDIO 204 . As mentioned above, two processing units cannot conveniently share and access their respective memory areas, especially the ARM system will not be ab...

Abstract

The invention discloses a data reading and writing method and an electronic device using the method. The electronic device includes: a first hardware system with a first operating system running on it; a second hardware system with a second operating system running on it; and a first read-write control unit located in the first hardware system. ; A second read-write control unit, located in the second hardware system; and a multi-port storage device; wherein the multi-port storage device includes a storage medium area for storing data; a first data interface for supporting the third a data transmission protocol; and a second data interface for supporting the second data transmission protocol; wherein the first operating system and the second operating system respectively communicate via the first data interface and / or the second The data interface performs reading and writing of the storage medium area, wherein the multi-port storage device receives read / write operations on the storage medium area from the first operating system via the first read-write control unit, and according to the The control of the first read-write control unit locks the reading / writing of the storage medium area to avoid conflicts when the second operating system performs read / write operations on the storage medium area.

Description

technical field [0001] The invention relates to the field of electronic equipment, and in particular to a data reading and writing method and electronic equipment using the data reading and writing method. Background technique [0002] In recent years, electronic devices such as mobile phones, tablet computers and personal digital assistants have become more and more popular. They have the advantages of light weight and simple touch operation, and they can easily surf the Internet, play games, watch videos, read magazines, etc. Features. With the continuous enhancement of hardware functions of electronic equipment, the same electronic equipment has been able to support two operating systems (such as etc.) run concurrently on it. In addition, electronic equipment systems based on hybrid (Hybrid) architectures have emerged. For example, it appears that by running OS X86 system and run The Hybrid system architecture composed of the ARM system of the operating system. ...
