Abstract

The present application provides an SHDSL (Single-pair High bit rate Digital Subscriber Line) data frame processing method and device. The method comprises: calling a drive layer in an FPGA (Field Programmable Gate Array) through an application layer in the FPGA, using the drive layer to execute initialization configuration of an SHDSL dedicated chip, and obtaining, after the configuration is successful, a status signal that indicates the configuration is successful; and starting conversion between an original data frame and a PCM (Pulse Code Modulation) code frame according to the status signal of the FPGA, and sending the converted PCM code to the SHDSL dedicated chip to generate a SHDSL data frame. Therefore, the SHDSL (Single-pair High bit rate Digital Subscriber Line) data frame processing method and device solve the problems in the prior art that the rate of the conversion between the original data frame and the PCM code frame is low, and that an SHDSL-related module is large in size and causes high difficulty in management and maintenance of software and hardware.

Description

technical field [0001] The present application relates to communication technology, in particular to a SHDSL (Single-pair High bit rate Digital Subscriber Line, symmetrical high-speed digital subscriber line) data frame processing method and device. Background technique [0002] Under the background of informatization construction, the scene monitoring of the field environment is becoming more and more common, which makes the research on the audio and video long-distance transmission technology of the scene in the field environment become very important. [0003] In the prior art, in order to improve the conversion rate between the original data frame and the PCM (Pulse Code Modulation, Pulse Code Modulation) code frame, a high-performance microprocessor hardware platform is usually used to complete the conversion between the original data frame and the PCM code frame. Communication format conversion; using a dedicated chip or ARM (Advanced RISC Machines, processor) micropro...
