Real-time task scheduling method and system based on multicore network processor

Abstract

The invention provides a real-time task scheduling method and system based on a multicore network processor. The real-time task scheduling system comprises a message receiving module, a task scheduling module, a task processing module and a message transmitting module, wherein the message receiving module is used for acquiring messages from the multicore network processor actively and transmitting the acquired messages to the task scheduling module; the task scheduling module is used for storing the received messages into a multistage work array and preserving a task status machine for each message; the task processing module is used for processing the messages in the multistage work array in a polling mode; the message transmitting module is used for transmitting the processed messages out. The real-time task scheduling method and system based on the multicore network processor has the advantages that on a multicore network processor platform, various hardware resources in the multicore network processor are made full use of and integrated, a high-efficiency task scheduling mechanism is achieved, and processing performance of task processing software in the multicore network processor is improved.

Description

technical field [0001] The invention relates to a task scheduling method based on a multi-core network processor platform, in particular to a real-time task scheduling method and system based on a multi-core network processor. Background technique [0002] With the continuous progress of the chip manufacturing process, the traditional single-core processor architecture technology has faced a bottleneck, and the integration of transistors has exceeded hundreds of millions. It also brings about an increase in power consumption. Therefore, multi-core processors emerge as the times require. By increasing the number of physical processors in the computer, the parallelism of threads can be effectively utilized to achieve parallel execution in the true sense. [0003] On-chip multi-core processor (CMP) is to integrate multiple computing cores in a single processor chip, thereby increasing computing power. Each microprocessor core is essentially a relatively simple single-threaded...
