Problems solved by technology
[0006] Therefore, there are the following problems in the prior art: the user layer task reads data from the RapidIO receiving buffer, which affects the RapidIO data transmission performance, especially when the data bursts, causing transmission blockage; at the same time, the data is moved from the kernel to the user layer. Data transmission of large size will cause a large delay; in addition, there is inter-core communication in user layer data forwarding, and synchronization and mutual exclusion will cause a large delay

Embodiment Construction
[0053] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, but not to limit the protection scope of the present invention.
[0054] figure 2 It shows a schematic flowchart of a data receiving and processing method provided in this embodiment, including:
[0055] S201. If the kernel layer receives a RapidIO (interconnection architecture) interrupt signal, acquire data, and store the acquired data in a reserved memory space.
[0056] Wherein, the kernel layer is an abstraction layer between internal hardware and software stacks of the base station.
[0057] The interrupt signal is an interrupt response signal generated according to an interrupt request sent by a peripheral when the CPU executes an instruction.
[0058] The data is the data required to perform task processing.

The embodiment of the invention discloses a data receiving and processing method and device, electronic equipment and a storage medium, and the method comprises the steps: if a kernel layer receives an interrupt signal of an interconnection system structure RapidIO, obtaining data, and storing the obtained data in a reserved memory space; when a user layer performs polling task processing, acquiring data from the reserved memory space to perform task processing. According to the embodiment of the invention, the acquired data is stored in the reserved memory space, so that the bus occupation of RapidIO can be released, the bus occupation time of RapidIO caused by data receiving and processing is effectively shortened, and transmission blockage during data burst is avoided; when the user layer performs polling task processing, the data is acquired from the reserved memory space to perform task processing, so data processing delay caused by data interaction between the kernel layer and the user layer is reduced, and delay caused by inter-process communication is avoided at the same time.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a data receiving and processing method, device, electronic equipment and storage medium. Background technique [0002] The C-RAN (Cloud-Radio Access Network, cloud computing-based wireless access network architecture) system is a distributed wireless network composed of remote radio frequency units (Remote Radio Unit, RRU) and antennas. It is a high-bandwidth, Low-latency optical transmission network, general-purpose processor and centralized baseband processing pool are composed of three major parts. At this stage, optical fibers are used to connect multiple base stations to form a base station pool. All baseband processing units (Base Band Unit, BBU) and remote radio frequency units are connected through a high-bandwidth, low-latency optical transmission network. The baseband processing units are concentrated at one physical site to form a baseband pool. Multipl...
