Problems solved by technology

Due to the large amount of video processing data and high timeliness requirements, traditional methods either need to consume a lot of CPU processing performance, or the timeliness requirements cannot be met
For example, patent CN104239249A discloses a data transmission method, which requires the PC to participate in the entire data transmission process, which consumes a lot of performance of the PC, and the memory of the PCI device itself is used in the data transmission process. are relatively small, greatly limiting the process of data transmission

Abstract

The invention provides a PCI heterogeneous system data fusion method, system and device and a storage medium, and the method comprises the steps of obtaining a user configuration file which comprises the space capacity required by the device; according to the space capacity required by the equipment, applying an available memory space of the equipment in a memory of the PC; acquiring data transmission demand information of each PCI device; allocating a first-level memory space for each PCI device in the available memory space of the device according to the data transmission demand information, and establishing a mapping relationship with the PCI device; and sending the space address of the allocated first-level memory space to the corresponding PCI device. By adopting the invention, the advantage of a large memory of the PC is fully utilized, the PC only needs to carry out master control scheduling without participating in data transmission in the whole process, the data is fused in the memory of the PC, and the PC can obtain the required data in time.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a PCI heterogeneous system data fusion method, system, equipment and storage medium. Background technique [0002] A heterogeneous system is generally composed of a PC (Personal Computer, personal computer) and an embedded platform. The PCI (Peripheral Component Interconnect) bus is a basic data transmission bus used on PCs and embedded platforms in heterogeneous systems, and supports a wide range of device types. Based on the PCI bus, each device in the heterogeneous system can play its own advantages. For example, the GPU (Graphics Processing Unit, GPU) can play its own advantages in graphics processing and parallel processing, and the CPU (Central Processing Unit, CPU) can play its own computing power. Advantage. [0003] Heterogeneous systems have been applied in video processing based on neural networks, which can collect video data from webcams and output recognit...
