Embodiment Construction

[0043] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0044] like figure 1 As shown, it is a schematic diagram of inter-core communication in the present invention. According to the flow direction of data during inter-core communication, the data core is divided into two types, one is the data sending core, and the other is the data receiving core. The two cores exchange data through the shared queue between the cores. The data sending core writes data into the shared queue, and the data receiving core reads data from the shared queue. The inter-core shared queue uses a ring queue. The advantage of the ring queue is that it ca...

Abstract

The invention provides an inter-core communication method and a core processor. The core communication method comprises that a data transmission core inputs data to a share queue which is between the data transmission core and a data acceptance core in bytes, and the data acceptance core reads the data from the share queue in the number of bytes of a data package. According to the inter-core communication method and the core processor, zero copy is achieved due to the fact that packaging operation of the data package is needless when the data are transmitted, the realization of modularization operation of inter-core communication is benefited due to the fact that a queue unit is set to be a corresponding data package when the data are received, and thus communication efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for inter-core communication and a core processor. Background technique [0002] With the development of wireless communication technology, some devices in the wireless communication system, especially some devices that perform wireless channel simulation in real time, often require calculation of large amounts of data. These devices usually use multiple core processors, and multiple cores perform channel simulation. Simulation calculation. [0003] The existing inter-core communication method is to send the data packet to the shared queue, unpack the data packet and then copy the data into the shared queue. This kind of inter-core communication method has low communication efficiency. Therefore, how to improve the inter-core Communication efficiency is an urgent problem to be solved.
