Embodiment 1

[0098] Such as figure 2 As shown, an electronic device comprising:

[0099] PCH unit 201;

[0100] SI / O unit 202, connected to the PCH unit 201;

[0101] The I / O expansion unit 203 is connected to the SI / O unit 202, wherein the I / O expansion unit 203 has at least one I / O interface;

[0102] Wherein, when a first external device is connected to the electronic device, the electronic device can establish communication with the electronic device through the first I / O interface of the at least one I / O interface, so that all The PCH unit 201 can perform data interaction with the first external device through the SI / O unit 202 and the I / O expansion unit 203 .

[0103] In a specific implementation process, the PCH unit 201 may specifically be a PCH chip, the SI / O unit 202 may specifically be a SI / O chip (super input-output chip), and the I / O expansion unit may specifically be a An I / O expansion chip.

[0104] In a specific implementation process, the electronic device may be a c...

Abstract

The invention discloses electronic equipment and a data interaction method. The electronic equipment comprises a PCH (platform controller hub) unit, an SI / O (super input / output) unit and an I / O extension unit, wherein the SI / O unit is connected with the PCH unit and the I / O extension unit, and the I / O extension unit is provided with at least one I / O interface. When first external equipment is connected with the electronic equipment, the electronic equipment can be communicated with the electronic equipment through a first I / O interface of the I / O interfaces, so that the PCH unit can be in data interaction with the first external equipment through the SI / O unit and the I / O extension unit.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to an electronic device and a data interaction method. Background technique [0002] Explanation of related terms: [0003] PCH: Platform Control Unit, English full name: Platform Controller Hub, is an integrated south bridge chip launched by Intel, responsible for communication between I / O buses, such as: PCI bus, USB, LAN, ATA, SATA, audio control controller, keyboard controller, real-time clock controller, advanced power management, etc. [0004] LPC interface: It is a new interface specification announced by Intel in 1997 to replace the traditional ISA BUS, and it is adopted by the industry in the form of free and open authorization. [0005] ESPI interface: Enhanced Serial Peripheral Interface, English full name: Enhanced Serial Peripheral Interface, the main feature is fast communication speed. Due to the defects of poor anti-interference ability and slow parall...
