Embodiment Construction

[0022] If there are 10 tasks that need 3 cores to process, task 0 gets a serial number 0 from the automatic numbering machine when entering the queue, so task 0 is put into the 0th unit of the array, and task 1 is obtained from the automatic numbering machine when entering the queue. The next sequence number 1 is obtained in the numbering machine, so task 1 is put into the first unit of the array...then these 10 tasks receive numbers from 0-9 respectively through an automatic numbering device, and are programmed into the in the queue array. This part is the enqueue operation of the task.

[0023] When the following core is idle, it receives the number that needs to be processed through another automatic numbering device: core 0 first obtains the serial number 0, then processes the task 0 corresponding to the 0th unit of the array, and at the same time, core 1 takes the next one from the automatic numbering device The sequence number is 1, so the task 1 corresponding to the ar...

Abstract

The invention relates to a visiting technology of the multinuclear processor system to the shared resource. It can improve the efficient when the multinuclear processor operates the alignment concurrently. The multinuclear can reach the operation of the in / out same queue by the automatic queue number device. The every nuclear reads the value of the register of the in-queue number to make sure the array location and judge the relation of the in-queue number and the out-queue number. If it accords to the correlation, the in-queue operation is done to the queue array, at the same time the automatic queue number device will add one digit to the present register; if not, the alarm will be returned to the present nuclear. The performance of treating the system by the multinuclear has improved greatly. The need of the hardware is low and simple and cost the source of the hardware little.

Description

technical field [0001] The invention relates to a technology for accessing shared resources by a multi-core processor system, in particular to a first-in-first-out queue multi-core parallel processing technology. Background technique [0002] With the rapid development of network communication technology, network customers have higher and higher requirements for the network, and the traditional single processor cannot meet the needs in terms of processing performance. Therefore, multi-core processors have been favored by more and more network equipment providers. . In a multi-core processor system, mutual exclusion of shared critical resources is one of the key factors affecting its performance. The current common practice is to implement mutual exclusion operations by locking shared resources, and queues are one of the main organizational forms of shared resources. [0003] In order to ensure mutual exclusion of queue operations between multiple cores, each core locks whe...
