Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention are described in detail below with reference to the accompanying drawings according to embodiments.
In the prior art, when data interaction is performed between SOCs and between processors having data processing and storing functions, the communication speed is slow, and for this problem, the present invention provides a data interaction method and a data interaction system implemented by using hardware, which are described in detail below with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a data interaction system provided in an embodiment of the present invention, and as shown in fig. 1, the system includes a first module and a second module having data operation and data storage functions, where the first module and the second module are both disposed with a high-speed signal controller.
In the data interaction system shown in fig. 1, a high-speed signal controller disposed on a first module is externally connected to a network controller (hereinafter referred to as a first network controller for convenience of distinction); externally connecting a high-speed signal controller deployed on the second module with a network controller (for convenience of distinguishing, hereinafter referred to as a second network controller); the first network controller and the second network controller are connected through a coupling device with a signal coupling function. In this way, the first module and the second module are connected by the first network controller, the coupling device with signal coupling, and the second network controller.
In the data interaction system shown in fig. 1, a first module may convert a data signal sent by its own high-speed signal controller into a network signal (hereinafter referred to as a first signal for convenience of distinction) after being processed by a first network controller, and transmit the network signal to a coupling device having a signal coupling function; the coupling device with the signal coupling function couples the first signal and transmits the first signal to the second network controller, and the first signal is processed by the second network controller and then converted into a data signal and transmitted to the high-speed signal controller of the second module. In the same way, the second module can convert the data signal sent by the high-speed signal controller into a network signal (for convenience of distinction, hereinafter referred to as a second signal) after being processed by the second network controller, and transmit the network signal to the coupling device with the signal coupling function; the coupling device with the signal coupling function couples the second signal and transmits the second signal to the first network controller, and the second signal is converted into a data signal after being processed by the first network controller and transmitted to the high-speed signal controller of the first module.
It can be seen that the coupling device with signal coupling function is mainly used in data interaction system for: and coupling a first signal sent by the first module to the second module through the high-speed signal controller and the first network controller of the first module and a second signal sent by the second module to the first module through the high-speed signal controller and the second network controller of the second module.
In the embodiment of the present invention, the first module and the second module may be two SOCs or two processors having data processing and data storage functions, respectively.
In the embodiment of the present invention, the coupling device with signal coupling function may be a transformer or a capacitor.
In the embodiment of the present invention, the high-speed signal controllers disposed in the first module and the second module may be USB controllers or PCIE controllers. And when the high-speed signal controller is a PCIE controller, the external network controller is a PCIE-PHY chip and the module where the high-speed signal controller is located needs to be provided with a PCIE-network card driver.
In practical application, the USB controller may be further divided into a USB2.0 controller and a USB3.0 controller, and different USB controllers and corresponding network controllers are also different, for example, when the high-speed signal controller is a USB2.0 controller, the external network controller should be a USB2.0 to hundred mega PHY chip; when the high-speed signal controller is a USB3.0 controller, the external network controller should be a USB3.0 gigabit PHY chip. In addition, when the high-speed signal controller is a PCIE controller, the external network controller PCIE converts a PHY chip, which may be a PCIE-to-hundred-megabyte PHY chip, or a PCIE-to-giga chip, and may be determined according to specific needs.
Therefore, in the present invention, there may be at least 6 system architectures according to the difference between the high-speed signal controllers in the first module and the second module, and the following description will be made of the 6 system architectures taking the first module and the second module as the SOC as an example:
