Problems solved by technology

The defect of the above method is obvious. Since the speed limit value of the CPU communication port is fixed, when the CPU is not "busy" and the communication port has a large amount of data to be processed, the valid data on the CPU port will be discarded. And the CPU is not fully utilized

Abstract

Embodiments of the invention disclose a method and a device for adjusting a data stream of a CPU (Central Processing Unit). The method comprises the following steps of obtaining a rate of current control data RC of CPU receiving control data RC; determining a range of the rate of the control data RC of the data stream according to a current idleness P of the CPU; and determining whether the rate of the current control data RC is within the range of the rate of the control data RC of the data stream, and if no, adjusting the rate of the current control rate RC within the range of the rate of the RC. According to the method and the device for adjusting the data stream of the CPU, which are disclosed in the embodiments of the invention, the current control data RC is computed through the current idleness P, and a scheme for adjusting the current control data is determined through the current idleness P, so that the effective management of the data stream of the CPU is realized, and the operation capacity of the CPU is improved under the condition that the service quality of the system is guaranteed.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of wireless networks, and in particular to a method and device for adjusting CPU data flow. Background technique [0002] As the 4G wireless network tends to be stable and mature, wireless network services such as wireless Internet access through 4G wireless communication terminals have been greatly popularized. In the requirements of relevant departments for wireless network security, a set of air interface monitoring equipment for all-round protection of 4G networks is required. [0003] In the field of mobile communication, 4G signal monitoring equipment is currently designed with a scheme similar to 4G base station equipment. However, due to the requirements for low power consumption, low cost, and personal portability of the equipment, the base station design scheme cannot be fully used. Therefore, such equipment usually Use chips with low power consumption and relatively low proc...
