Online updating method and chip

Abstract

The invention discloses an online updating method and a chip, and relates to the technical field of communication. The online updating method solves the problem that when a mainly used processor is updated in the prior art, normal operation of service is interrupted. The online updating method is applied to the chip, the chip comprises at least one mainly used processor which is connected with a standby processor through a bus, the chip is connected with a network managing unit through a bus, when the mainly used processor and the standby processor are successfully synchronized, the mainly used processor sends a success synchronization message to the network managing unit, the network managing unit sends a first start-working order to the standby processor and sends a first stop-working order to the mainly used processor, the standby processor is used for processing a data frame corresponding to the serial number of the next data frame to be processed by the mainly used processor, the mainly used processor stops working, and the network managing unit updates the mainly used processor. The online updating method is applied to updating of the chip.

Description

technical field [0001] The invention relates to the field of communication technologies, and in particular, to an online upgrade method and chip. Background technique [0002] With the continuous evolution of wireless access systems, in order to meet the increasing bandwidth requirements of users, wireless access systems are rapidly developing in the direction of MBB (Mobile Broadband, mobile bandwidth), which requires a wireless backhaul (backhaul transmission) system in the physical layer. The development of high-capacity, high-performance, and IP (Internet Protocol, the protocol for interconnection between networks), therefore, the physical layer chip is developed from a simple logic (logic circuit) ASIC (Application Specific Integrated Circuit, application-specific integrated circuit) chip. It is a Soc (System on chip, system on chip) chip that combines logic and DSP (Digital Signal Processor, digital signal processor) or CPU (Central Processing Unit, central processing ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the upgrade of the physical layer chip is to interrupt the operation of the physical layer chip during the time period when the network traffic is small, such as at night, and restart the chip after the service upgrade in the chip is completed, which affects the normal operation of the service. run
