Abstract

The present invention relates to a direct memory access control method, device and physical layer accelerator card, wherein the direct memory access control method comprises the following steps: obtaining a service packet request of a channel queue; detecting the channel queue corresponding to the service packet request Flow control status, DMA transceiver status, and channel priority; according to the detected flow control status of the channel queue, or / and, DMA transceiver status, or / and channel queue priority, channel arbitration is performed on the channel queue; if the result of the channel arbitration If it is passed, select the corresponding DMA transmission channel of the channel queue to transmit the service package data requested by the service package. The embodiment of the present invention can realize the accelerated DMA process of the physical layer, and improve the data throughput and data transmission efficiency.

Description

technical field [0001] The invention relates to the technical field of mobile communication transmission, in particular to a direct memory access control method, device and physical layer acceleration card. Background technique [0002] With the rapid development of the mobile Internet, especially the development of 5G (5th-Generation, fifth-generation mobile communication technology) communication technology, it is required to have deep coverage, high security, ultra-high reliability, ultra-low delay, extreme data rate and Extreme capacity and other communication features. The extreme 1 data rate and ultra-low latency communication characteristics put forward higher requirements for physical layer processing, and it is difficult to meet the processing requirements of the physical layer by using a conventional CPU (Central Processing Unit, central processing unit). [0003] During the implementation process, the inventors found that at least the following problems existed i...
