Embodiment Construction

[0033] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0034] First, the application scenarios involved in the embodiments of the present application are described.

[0035] At present, in order to improve the processing performance of the computer device, some functions implemented by the processor are offloaded to the first device, and the first device completes command processing. For example, a SoC can be connected to a computer device, and the hardware accelerator set in the SoC can assist the application in the computer device to process commands. Specifically, after the computer device is connected to the SoC, the application in the computer device can transmit some commands that need to be processed. For the SoC, the driver module and accelerator in the SoC can process these ...

Abstract

The invention discloses a data transmission method and apparatus, a first device and a server. The method comprises the following steps: when the execution result of a first command in an SQ is received, the first device modifies the execution state of the first command in a command state table to be completed; when the execution result of the first command in the SQ is received, the first devicemodifies the execution state of the first command in the command state table to be completed; the first device determines that the execution states of the first n commands recorded in the command state table are all completed, and the first n commands are at least one command sequentially stored in the SQ; the first device sends the processing data of the first n commands to the application according to the storage order of the first n commands in the SQ, and the processing data of the first n commands includes the execution results of the first n commands. As such, the order in which the SoCreturns process data to the application and the order in which the SoC transmits commands to the SoC can be ensure to be consistent, and the SoC preserves the order of the commands, thereby effectively avoiding logical confusion of the application and satisfying application requirements.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a data transmission method, device and equipment. Background technique [0002] With the development of computer technology, other devices are often connected to computer equipment for command processing. For example, a system on chip (SoC) can be connected to a computer device, and a hardware accelerator is provided in the SoC, which can assist applications in the computer device to process commands, thereby improving the system performance of the computer device and increasing the system processing speed. [0003] Currently, if figure 1 As shown, the SoC is provided with a driver module, an accelerator, a submission queue (submission queue, SQ) and a completion queue (completion queue, CQ). The application transmits the command to the SoC; the driver module in the SoC adds the command to the SQ; the accelerator in the SoC fetches the command from the SQ and execut...
