Abstract:
1. An electronic device, comprising: a core unit including a first Peripheral Component Interconnect Express (PCIe) port and a second PCIe port; a peripheral device including a PCIe port; a Thunderbolt connector; a Thunderbolt control unit coupled to the Thunderbolt connector, wherein the Thunderbolt control unit includes a host mode and an end-point device mode; a first switch circuit, wherein, a first common terminal of the first switch circuit is coupled to the PCIe port of the peripheral device, and a first selection terminal of the first switch circuit is coupled to the first PCIe port of the core unit; and a second switch circuit, wherein a common terminal is coupled to a first PCIe port of the Thunderbolt control unit, a first selection terminal of the second switch circuit is coupled to the second PCIe port of the core unit, and a second selection terminal of the second switch circuit is coupled to a second selection terminal of the first switch circuit, wherein the Thunderbolt control unit selectively operates at the host mode or the end-point device mode according to a user command or whether the core unit is enabled or not, when the Thunderbolt control unit operates at the host mode, the first common terminal of the first switch circuit is coupled to the first selection terminal of the first switch circuit, the first common terminal of the second switch circuit is coupled to the first selection terminal of the second switch circuit; and when the Thunderbolt control unit operates at the end-point device mode, the first common terminal of the first switch circuit is coupled to the second selection terminal of the first switch circuit, the first common terminal of the second switch circuit is coupled to the second selection terminal of the second switch circuit.
