Problems solved by technology

[0004] However, if the above-mentioned method is used to send data packets, the CPU will need a large amount of time to process the interruption of the input and output devices and other related affairs when the data flow is particularly large. The bottleneck of data traffic processing capability; on the other hand, in order to meet the high-speed data packet transmission requirements, high-performance CPU may bring more power consumption overhead

Embodiment Construction

[0030] As described in the background technology, if the method in the prior art is used to send data packets, there will be a lot of time for the CPU to process the interruption of the input and output devices and other related affairs when the data flow is particularly large. The processing capability of the CPU will become the bottleneck of the data traffic processing capability of the computer device; on the other hand, in order to meet the requirements of high-speed data packet transmission, a high-performance CPU may bring more power consumption overhead.

[0031]In the technical solution of the present invention, by setting the data packet transmission accelerator, the data transmission between the input and output devices can be realized without the participation of the CPU; thus, the load of the CPU will not be increased when the data flow is large, and the same Higher data traffic can be supported under the CPU resource, and the CPU performance can be improved. In ad...

Abstract

A data packet transmission device and system, the data packet transmission device includes: a CPU; a data packet transmission accelerator, adapted to provide an input interface and an output interface, the input interface receives the data packet descriptor of the data packet sent by the sending device, and the The output interface outputs the data packet descriptor to the receiving device, so that the receiving device can obtain the data packet according to the data packet descriptor, and the sending device and the receiving device are selected from input and output devices and the CPU . The technical scheme of the invention can reduce the load of the CPU and improve the performance of the CPU.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data packet transmission device and system. Background technique [0002] There are usually some data packet input and output devices in the computer device, such as Universal Serial Bus (Universal Serial Bus, USB), Secure Digital Input and Output (Secure Digital Input and Output, SDIO), high-speed serial computer expansion bus (peripheral component interconnect express, PCIE), etc., if necessary, the computer device will also include a modem (MODEM). The data packets interact with the central processing unit (Central Processing Unit, CPU) through these devices. In some scenarios, data packets need to be transmitted from some devices to other devices. [0003] In the prior art, the CPU operates the input and output devices in an interrupt or polling manner. Especially to transmit data packets from one I / O device to another I / O device, it needs to go through the process of ...
