Method and system for capturing and storing bare nucleus exception in multi-core processor

Abstract

A method and system for capturing and storing the exception of bared core in multi-cores processor. The method comprises the steps of: the control plane core creating an exception guarding task, the exception guarding task running and creating the shared queue between the control plane core and the data plane core; the data plane core initializing the exception processing after running, setting an exception vector table, hooking the exception service routine by setting the exception vector table, and creating an exception processing task; after the exception occurs in the data plane core, the processor capturing the exception information, calling back the exception service routine to take over the processing, releasing an exception processing semaphore to inform the exception processing task; after the exception processing task obtains the semaphore, saving the exception information, processing it and then writing the exception information and the processed result into a shared queue; the exception guarding task polling the shared queue regularly, when discovering the exception information in the queue, fetching it to write in the memory.

Description

technical field [0001] The invention relates to the field of processors, in particular to a method and system for capturing and storing exceptions when a bare core of a multi-core processor is used in the communication field when an exception occurs. Background technique [0002] With the advent of the information age and the emergence of various new technologies and services, users have higher and higher bandwidth requirements for both mobile communication and data communication. In order to meet the high bandwidth requirements of individual users, operators require mobile communication equipment And data communication equipment has large capacity, high access and high processing performance. In order to meet the requirements of large capacity, high access and high processing performance, a large number of multi-core processors with high processing capabilities have been used in mobile communication devices and data communication devices. [0003] A multi-core processor is...
