System switching unit having a switch to switch on/off a channel for data interaction between a first system and the bus interface of a second system according to the operation state of the second system

A hybrid-system computer comprising a first system, a second system and a power supply unit, wherein the power supply unit is connected to the first system and the second system, respectively, and wherein power consumption in an operating state of the second system is lower than that in an operating state of the first system, the hybrid-system computer further comprising:

• a triggering unit configured for obtaining a switching command when the first system is in an operating state and the second system is in a non-operating state;
• and
• a switching unit connected to the triggering unit, the first system and the second system, respectively, and configured for receiving the switching command and controlling the first system to enter a non-operating state and the second system to enter an operating state based on the switching command;
• wherein the switching unit is implemented as a hardware unit comprising a first switch connected between the first system and an internal low-speed bus interface of the second system, and a second switch connected between the first system and an internal high-speed bus interface of the second system,
• wherein the first switch is configured to, when the second system transits from the non-operating state to the operating state, switch input of an input device of hybrid-system computer from the first system to the second system, and
• wherein the second switch is configured to switch on and off a channel for data interaction between the first system and the internal high-speed bus interface of the second system, according to the operation status of the second system.
