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

Embodiment Construction

[0030] Such as figure 2 As shown, it is the logical unit structure adopted by the present invention to achieve the above object, the communication between the micro-engine and the core processor is completed through the ring queue and the shared memory, and the messages transmitted between the two are directly added to the ring queue UA_TxQ , In UA_RxQ, there is no need for an interlock mechanism, where:

[0031] The communication task is used to be responsible for the core processor ARM to receive the data message in the UA_TxQ queue, copy the data and encapsulate the process message, and send it to the designated processing process; in addition, it can regularly detect the communication receiving queue 204, if there is a message in the queue, Notify the microengine communication receiving thread 202 to receive the message that the core processor ARM sends to the microengine UE;

[0032] The microengine communication receiving thread (UA_RxThrd) 202 is used to extract messa...

Abstract

The invention is a method of communicating between kernel processor and microengine in a network processor, setting annular queue and shared memory between them, directly placing messages transmitted between them in the transmit-receive annular queue, and it includes the flows: the microengine transmits messages to the kernel processor for processing and the kernel processor transmits messages to the microengine for processing. Compared with existing techniques, the microengine communicates with ARM by using the annular queue, which can make ARM communication task operating queue avoid adopting locking mechanism, accordingly avoiding the reduction of processing performance of the microengine. At the same time, it can extremely enhance processing performance of network processor, so as to complete data processing and transmission at limited speed, playing a great role in increasing throughput and processing speed of 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 flexi...
