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 adopting the same. The electronic device comprises a first hardware system on which a first OS (operating system) runs, a second hardware system on which a second OS runs, a first reading and writing control unit located in the first hardware system, a second reading and writing control unit located in the second hardware system, and a multi-port storage device, wherein the multi-port storage device comprises a storage medium zone used for storing data, a first data interface used for supporting the first data transmission protocol, and a second data interface used for supporting the second data transmission protocol; the first OS and the second OS perform reading and writing for the storage medium zone through the first data interface and / or the second data interface respectively; the multi-port storage device receives the reading / writing operation on the storage medium zone from the first OS through the first reading and writing control unit, and performs locking for the reading / writing of the storage medium zone under the control of the first reading and writing control unit, so as to avoid conflict when the second OS performs reading / writing operation on the storage medium zone.

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. Function. 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. ...
