Data interaction method and device

Abstract

The invention provides a data interaction method and system. The data interaction system comprises a first module and a second module, wherein the first module and the second module have data operation and data storage functions; a high-speed signal controller is deployed in the first module, and the high-speed signal controller is externally connected with a first network controller; a high-speedsignal controller is deployed in the second module, and the high-speed signal controller is externally connected with a second network controller; and the first network controller and the second network controller are connected through a coupling device with a signal coupling function. The method is applied to the data interaction system, and comprises the following steps: utilizing the couplingdevice with the signal coupling function, and coupling a first signal sent to the second module by the first module through the high-speed signal controller and the first network controller of the second module, and a second signal sent to the first module by the second module through the high-speed signal controller and the second network controller of the second module.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data interaction method and device. Background technique [0002] A system on chip (System on Chip, SOC) can be understood as a system that integrates a microprocessor, analog IP core, digital IP core, and memory on a single chip, with functions such as data calculation and storage. [0003] In the prior art, there are many methods for data interaction between two SOCs, such as UART, I2C, SPI and other communication methods. Among them, although the UART communication method has no master-slave relationship and can communicate bidirectionally, the communication speed is slow (generally commonly used) The rate is 115.2Kbps); I2C and SPI communication methods have a master-slave relationship, and the slave device cannot actively send data to the master device, which is limited in practical applications, and the communication speed is relatively slow (the commonly used r...

Problems solved by technology

[0003] In the prior art, there are many methods for data interaction between two SOCs, such as UART, I2C, SPI and other communication methods. Among them, although the UART communication method has no master-slave relationship and can communicate bidirectionally, the communication speed is slow (generally commonly used) The rate is 115.2Kbps); I2C and SPI communication methods have a master-slave relationship, and the slave device cannot actively send data to the master device, which is limited in practical applications, and the communication speed is relatively slow (the commonly used rate is I2C 400Kbps, SPI 33Mbps)

[0004] In addition, communication methods such as UART, I2C, and SPI can also be used for data interaction between processors with functions such as data calculation and storage (such as CPU+PCH of Intel X86 platform, independent graphics card module of Nvidia, etc.), but There is also the limitation of master-slave relationship and the problem of slow communication speed
