Problems solved by technology

This kind of lock conflict phenomenon, because the pipeline that has not taken the cache space needs to wait until the cache space is obtained before further processing the message, which will reduce the parallel processing capability of the multi-core processor, resulting in a waste of processing core resources

Embodiment Construction

[0042] The message forwarding method based on the multi-core processor and the multi-core processor provided by the present invention will be described in more detail below with reference to the drawings and embodiments.

[0043] An embodiment of the present invention provides a message processing method based on a multi-core processor, such as figure 1 shown, including:

[0044] Step 101, in the process of creating pipelines, the multi-core processor allocates a cache subpool for each pipeline, and the cache subpool is used to store message pointers, and the pointers point to message buffers.

[0045] Among them, each message pointer corresponds to a message, and each message corresponds to a message buffer, and each message pointer points to the message buffer of the message corresponding to the message pointer, and the message buffer is actually stored The physical area of ​​the packet. Specifically, the message pointer points to the address of the physical area where the...

Abstract

The invention provides a multi-core processor based message processing method and a multi-core processor. The method comprises steps as follows: the multi-core processor distributes one buffer subpool to each assembly line in a flow line establishing process, and the buffer subpool is used for storing a message pointer which points to a message buffer; and the received messages are scattered to the buffer subpools corresponding to different flow lines and processed on the corresponding flow lines. According to the multi-core processor based message processing method and the multi-core processor, one buffer subpool is provided for each flow line, and resources are directly acquired from the corresponding buffer subpools when required to be acquired for the flow lines, so that the lock confliction phenomenon among the flow lines in the prior art is avoided, lockless message retransmission is realized, and the parallel processing capability of the multi-core processor is improved to a certain degree.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a message processing method based on a multi-core processor and the multi-core processor. Background technique [0002] At present, in order to meet the requirements of high-speed data forwarding performance, multi-core processors are more and more popular, and the multi-core processors have high scalability and parallel computing capabilities. The so-called multi-core processor is a processor that integrates multiple core processors on a hardware chip, usually in a shared memory structure. The multi-core processor has multiple processing cores independent of each other, and can execute message processing programs in parallel, thereby enhancing the throughput of the system. At present, the scheme of using the multi-core processor to process messages is as follows: [0003] (1) The processing of the message is divided into multiple processing stages, and different p...
