Problems solved by technology

[0003] The user can switch between the main system and the subsystem at any time as needed. In the prior art, when switching from the main system to the subsystem, the main system will send a shutdown command to the hardware device (such as a touchpad, keyboard, etc.), and the subsystem needs to be restarted. Activate some hardware devices before they can be used. When switching from the subsystem to the main system, the main system also needs the same activation operation. The above-mentioned reactivation of the hardware device will prolong the startup speed and waste power resources.

Abstract

The invention provides a computer and a computing system. The computer comprises a first system, a second system, a shared hardware device and a control device. The first system comprises a first hardware system, and the first hardware system is used to support the running of a first operating system. The second system comprises a second hardware system, and the second hardware system is used to support the running of a second operating system. The control device is respectively connected with the first system, the second system and the shared hardware device to keep the shared hardware device in an active state during the switching process from the first system to the second system, and the active state means the enabled state of the hardware system after the initialization of the system. By using the system, the shared hardware device is kept in the active state when switching among multiple systems without the repeated execution of the activating operation of the shared hardware device.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a computer and a computing system. Background technique [0002] Shorter start-up time and longer battery life are the goals that notebook computer designers are always pursuing, and notebook computers with instant power-on (LatitudeON) function have emerged for this goal. A notebook computer with instant power-on function has two completely independent systems: the main system entered under the normal power-on module and the subsystem entered under the instant power-on mode. The main system is mainly composed of CPU, operating system (such as Windowns, etc.), The subsystem is mainly composed of an ARM (Advanced RISC Microprocessor, advanced RISC microprocessor) low-power processor, a small operating system (such as WinCE, etc.), and an application program. When using the subsystem, only a limited number of hardware devices such as touchpad (Touchpad), keyboard (Keyboard), wirel...
