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] Such as 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...

Abstract

The present invention provides a method for inter-core communication and a core processor, wherein the method for inter-core communication includes: the data sending core writes to the shared queue between the data sending core and the data receiving core in units of bytes input data; the data receiving core reads data from the shared queue in units of the number of bytes of the data packet. The above-mentioned inter-core communication method and the core processor do not need to perform packet packaging operations when sending data, and realize zero copy; when receiving data, the queue unit is set to the corresponding data packet, which is convenient for realizing the module of inter-core communication Operation; thereby improving the efficiency of communication.

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. Contents of the invention [0004] Embodiments of the present invention provi...
