Abstract

The invention provides a multiprocessor signal processing equipment rapid fault recovery method and a system thereof. The multiprocessor signal processing equipment rapid fault recovery method comprises the following steps: in response to the occurrence of a fault of a first processor, storing a communication middleware state and a fault recovery mark of the first processor in a nonvolatile memory; protecting the code segment of the system firmware operated by the first processor in the memory, so that the first processor is subjected to soft reset; after the first processor is reset and restarted, running the boot firmware, accessing the nonvolatile memory by the boot firmware, acquiring an entry address of the code segment in the memory by the boot firmware in response to a failure recovery mark stored in the nonvolatile memory, and executing the system firmware through an instruction executed from the entry address; enabling the first processor to execute the system firmware to obtain the stored state of the communication middleware so that the first processor can be added into the communication group to which the first processor belongs when the first processor breaks down again; enabling the first processor to execute the system firmware to perform a task processing cycle.

Description

Technical field [0001] This application relates to reliability and fault tolerance, and in particular, to a method and system for rapid failure recovery after a node in a multiprocessor signal processing device fails. Background technique [0002] High-performance signal processing equipment usually adopts an architecture based on multi-core and multi-processor collaborative computing, and the computing tasks for signal processing are shared among multiple processors or processor cores. In addition to computing, multiple processor cores or processors also frequently communicate to distribute and / or collect computing tasks and synchronize the progress of computing tasks. Run software on the processor core or processor to control the signal processing process. The software that runs is large in scale, complex in flow, and implements a variety of complex algorithms. It also includes communication middleware to manage the communication between processors or processor cores. . [0003...
