Problems solved by technology
However, during the reconstruction process of the dynamic area, the data interaction between the static area and the dynamic area is interrupted. Even though the dynamic reconstruction time of the FPGA is generally at the millisecond level, for data processing occasions with strict real-time requirements, The interruption of data processing caused by reconstruction also directly affects the reliability of data processing
Therefore, the present invention proposes a transient reliable processing method for heterogeneous multi-source data reconstruction, which can solve the problem of interruption of data interaction between the static area and the dynamic area when the FPGA is dynamically reconfigured, and can realize heterogeneous multi-source reliable processing of data

The invention discloses a reliable processing method for heterogeneous multisource data in a reconstruction transient state. The method comprises the steps of judging a state of a dynamic region of anFPGA; establishing a BRAM in a static region of the FPGA to cache data at a reconstruction moment; after reconstruction, sending an inquiry frame to the static region by the dynamic region of the FPGA, wherein the inquiry frame comprises coordinates of the dynamic region in a physical region of an FPGA chip and a function ID of a reconstruction code running in the dynamic region; and analyzing the inquiry frame sent by the dynamic region through the static region of the FPGA, and returning a response frame, wherein the response frame comprises the data cached in the BRAM at the reconstructionmoment. According to the method disclosed by the invention, the problem of interrupt of data interaction between the dynamic region and the static region during dynamic region reconstruction due to faults or function switching of the dynamic region of the FPGA can be solved, so that the reliability of heterogeneous multisource data processing is improved.
Description
technical field [0001] The invention belongs to the fields of electronic engineering and computer science, and in particular relates to a transient reliable processing method for heterogeneous multi-source data reconstruction. Background technique [0002] With the proposal of the national strategy "Made in China 2025", intelligent manufacturing has become a hot term in contemporary China. However, the realization of intelligent manufacturing is inseparable from data. These data are more specifically expressed as data on the manufacturing site. Therefore, the reliable collection, processing, exchange and transmission of manufacturing site data is the underlying technical support for the realization of intelligent manufacturing. The data at the manufacturing site is heterogeneous in terms of data protocol and multi-source in terms of data volume. How to efficiently process heterogeneous multi-source data while ensuring the reliability of data processing is very important. Du...
