Inter-chip communication method, device and system and storage medium

Abstract

The embodiment of the invention provides an inter-chip communication method, device and system and a storage medium, and the method is used for a first chip, and comprises the steps: determining first transmission data to be transmitted to a second chip; writing the first transmission data into a first ring buffer area; updating write pointer information of the first management storage space; and sending first notification information to the second chip, the first notification information being used for indicating the second chip to read the first transmission data from the first ring buffer, and updating read pointer information of the first management storage space based on a read operation of the first transmission data. Through the inter-chip communication method provided by the embodiment of the invention, the occupation of a storage space can be reduced, and the data transmission efficiency is improved.

Description

technical field [0001] The present invention relates to the field of data communication, and in particular, to an inter-chip communication method, device, system and storage medium. Background technique [0002] With the advent of the era of big data and the Internet of Things, the amount of data is increasing explosively, and the requirements for hardware communication are also increasing. At the same time, the data volume and transmission frequency of data transmission between chips are gradually increasing, posing challenges to data transmission between chips. The traditional communication between two chips includes the transmission of data. [0003] The current inter-chip data transmission method often needs to open up a shared cache area in both the sender chip and the receiver chip, which wastes memory space; moreover, in the inter-chip data transmission method implemented through the PCIe interface, due to the provisions of the PCIe interface, the first The chip and...

Problems solved by technology

[0003] In the current inter-chip data transmission method, both the sender chip and the receiver chip need to open up a shared buffer area, which wastes memory space; The chip and the second chip need to be in EP mode and RC mode respectively. When the first chip needs to write data to the second chip, the first chip needs to write the data into the local buffer for the second chip to store the data through PCIE. into the local buffer of the second chip; when the first chip needs to read data from the second chip, the first chip needs to prepare the local buffer and notify the second chip to write data to the local buffer through PCIE

The above method not only has low data transmission efficiency, but also only the first chip can be the dominant party to send commands, that is, without the permission of the first chip, the second chip can neither actively send data to the first chip nor actively read The data of the first chip, such inter-chip communication is unequal
