Communication method between kernel processor and micro-engine in network processor

Abstract

A communication method between a core processor and a micro-engine in a network processor, by setting a ring queue and a shared memory between the micro-engine and the core processor, and directly storing the messages transmitted between the micro-engine and the core processor Into the sending and receiving circular queues, including the flow of the micro-engine sending the message to the core processor and processing it and the process of the core processor sending the message to the micro-engine and processing it, compared with the existing technology In the present invention, the ring queue is used when the micro-engine communicates with the ARM, so that the ARM communication task operation queue can avoid using a locking mechanism, thereby avoiding the problem of the micro-engine processing performance degradation due to ARM's high-priority blocking or preempting thread resources. At the same time, the processing performance of the network processor can be greatly improved, so that when it is applied in a wireless mobile communication system, it can complete data processing and forwarding at a limited speed, which has a great effect on improving the throughput and processing speed of the system.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a communication method between a core processor and a micro-engine in a network processor in the field. Background technique [0002] At present, with the rapid development of wireless communication technology, the data flow that needs to be processed in wireless communication systems is increasing, and the requirements for data processing speed are also getting higher and higher. Single boards implemented by general-purpose processors have been unable to complete data processing. Fast processing and forwarding of packets. Therefore, in the field of wireless communication, a dedicated network processor is selected instead of a general-purpose processor. [0003] Intel's IXP1200 network processor is the first network processor that combines multiple micro-engines with embedded microprocessors. This highly integrated processor not only provides flexib...

Problems solved by technology

[0006] The purpose of the present invention is to provide a kind of communication method between the core processor in the network processor and the microengine, to overcome the problem of preempting or blocking the microengine thread resources due to the high priority of the ARM when ARM and the microengine communicate in the current network processor. The shortcomings that lead to the performance degradation of the network processor, thereby improving the performance of the network processor, and this communication method is also applicable to other types of network processors of Intel Corporation
