Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] FIG. 1 is a schematic diagram of a media stream processing flow in the present invention. As shown in the figure, the lower-level device sends data to the CPU, and the CPU protocol stack combines several single packets of the media plane into one package according to the format of the package, and adds the package data before the data package according to the format of the package After the header is sent to the logic; the logic splits the received combined data into single packets for corresponding processing, and provides the processed single packet data to the upper-level equipment; for the data single input from the upper-level equipment to the logic media Packet, the logic combines several single packets of the media plane into a data packet according to the format of the packet, and adds the header of the packet before th...

Abstract

The invention discloses a media stream data processing method for reducing processing load of CPU. According to a merging package format, the logic of equipment combines a plurality of media surface single packages into one merging package, then the merging package data is sent to a CPU protocol stack to process, the CPU protocol stack divides received merging package data into single packages and provides to a lower device to process; according to the merging package format, the CPU of the device combines a plurality of media surface single packages into one merging package, then the merging package data message is provided to the logic to process, the logic divides received merging package data into single packages and does corresponding treatment, then transmits to an upper device to proccess. The method of the invention only does certain alteration to the format of received / transmitted packages, increases processing flow of the format message through the CPU protocol stack and the logic, reduces the number of interruption, gets effect of reducing processing load of CPU and reduces equipment cost and energy consumption.

Description

technical field [0001] The invention belongs to the technical field of data transmission, and particularly relates to a method for reducing the central processing unit (Central Processing Unit, abbreviated as BTS) when performing data communication on the base station (Base Transceiver Station, abbreviated as BTS) side of a CDMA (Code Division Multiple Access) system. CPU) processing load data processing method. Background technique [0002] Commonly used embedded multi-Ethernet communication devices are generally composed of CPU units, memory units, Ethernet chips and hardware logic units. Now commonly used hardware logic is Field Programmable Gate Array (Field Programmable GateArray, abbreviated as FPGA), Erasable Programmable Logic Device (abbreviated as EPLD), etc., hardware logic cooperation can complete physical signal and data Processing capacity, in some applications, can replace the CPU to complete the data processing work. [0003] At present, in the BTS base sta...
