Method for realizing multi-core processor external communication in distributed system

Abstract

The invention is to provide a method for realizing the external communication of a multi-core processor in a distributed system. The multi-core processor receives information by the steps: a multi-core processor single-board control surface network port 101 receives information sent by other single board and transfers the received information to a shared internal memory 103 based on the shared internal memory pointer; simultaneously a distributor 102 in the multi-core processor extracts dentification information from the received information; the distributor 102 figures out a matching control surface nuclear based on the identification information of the received information and sends notification information to the matching control surface nuclear, the notification information carries the shared internal memory pointer of the received information; the matching control surface nuclear receives the notification information and then transfers the received information from the shared internal memory 103 to other receive queues according to the pointer in the notification information, extracts the received information for further processing. The method is also suitable for the control surface with a plurality of network ports and has good expansibility.

Description

technical field [0001] The invention relates to the field of processors, more specifically, to a method for external communication of multi-core processors in a distributed mobile communication system. Background technique [0002] With the rapid development of mobile communication technology, more and more terminal users use mobile communication. In order to ensure call quality and bandwidth when terminal users use voice services and data services, mobile operators have higher and higher requirements for scalability of mobile system equipment. In order to meet scalability requirements, most mobile communication devices currently adopt a distributed system architecture. [0003] For a mobile communication system using a distributed system architecture, most of the system equipment is composed of an interface board, a media plane processing board, and a control plane processing board. The interface board is responsible for sending and receiving external messages and separat...
