Problems solved by technology

The main problem with this kind of dynamic kernel loading is that whenever a dynamic kernel needs to be loaded, an operation command on the host side is required, and the software needs to interact with the underlying hardware, which is not real-time, resulting in additional delays

Abstract

The embodiment of the invention discloses a multi-dynamic-core loading method and device and a medium, and the method comprises the steps of reading a reconfiguration data flow from a preset storage space when the loading start of a dynamic core is detected; and loading the dynamic core according to the original data stream carried in the reconfiguration data stream; when the reading address carried in the reconfiguration data stream is not the ending address, reading the next reconfiguration data stream from the storage space according to the reading address carried in the reconfiguration data stream, and returning to the step of loading the dynamic core corresponding to the original data stream according to the original data stream carried in the reconfiguration data stream. By reading the reconfiguration data stream from the storage space, loading operation commands of a software level can be reduced. In addition, the reading address of the next data stream is added to each reconfiguration data stream, the FPGA can achieve automatic loading of the dynamic core depending on the reading address, the FPGA does not need to be triggered through a software layer when the dynamic coreis loaded each time, and the loading efficiency of the dynamic core is improved.

Description

technical field [0001] The present invention relates to the technical field of hardware configuration, in particular to a multi-dynamic core loading method, device and computer-readable storage medium. Background technique [0002] In recent years, a reconfiguration (Partial Reconfiguration) function has been widely used in a Field Programmable Gate Array (FGPA). Reconfiguration mainly refers to dividing the entire FPGA into a static area and a dynamic area. During system operation, the logic functions of the dynamic area can be reconfigured. [0003] At present, when the compilation results of multiple dynamic kernels (kernels) need to be loaded, the existing method is generally to execute an operation command at the software level (host side) to load the first dynamic kernel kernel; when it is necessary to load another dynamic kernel When using the kernel, the host needs to input an operation command again to load another dynamic kernel. The main problem with this kind o...
