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

The invention provides a method, system, equipment and storage medium for data fusion of PCI heterogeneous systems. The method includes: acquiring a user configuration file, where the user configuration file includes the space capacity required by the device; Apply for the available memory space of the device in the memory; obtain the data transmission requirement information of each PCI device; allocate the first-level memory space for each PCI device in the available memory space of the device according to the data transmission requirement information, and establish a mapping relationship with the PCI device; Send the space address of the allocated first-level memory space to the corresponding PCI device. By adopting the present invention, the advantages of the large memory of the PC are fully utilized, the PC only needs to perform main control scheduling, and does not need to participate in the data transmission in the whole process.
Description
technical field [0001] The invention relates to the technical field of data processing, in particular to a data fusion method, system, device and storage medium of a PCI heterogeneous system. Background technique [0002] A heterogeneous system is generally composed of a PC (Personal Computer, personal computer) machine and an embedded platform. PCI (Peripheral Component Interconnect, Peripheral Component Interconnect Standard) 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 a heterogeneous system can play its own advantages. For example, a GPU (Graphics Processing Unit, GPU) can play its own graphics processing and parallel processing advantages, and a CPU (Central Processing Unit, CPU) can play its own computing. Advantage. [0003] Heterogeneous systems have been applied in neural network-based video processing, which can collect video data f...
