Abstract

The invention discloses a field programmable gate array (FPGA) upgrading method and device. The method includes the steps: a plurality of FPGA(s) read corresponding upgrading files from the same memory, wherein the memory stores the upgrading files corresponding to the plurality of FPGA(s) in advance; and the plurality of FPGA(s) are upgraded according to the corresponding upgrading files. The technical problem that the upgrading efficiency of the plurality of FPGA(s) is low without an external control unit in the prior art can be overcome.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a field programmable gate array upgrading method and device. Background technique [0002] With the increase in the complexity of system applications, it has become an inevitable trend to introduce multiple Field Programmable Gate Arrays (Field Programmable Gate Array, referred to as FPGA) in a system. Multiple FPGAs undertake different tasks respectively. Take the security industry as an example. , with the increasing rise of the security industry, the security application scenarios have also changed from point to surface, from single to integrated, so that the functional integration and complexity of security equipment are increasingly required. Therefore, many devices integrate several or even several Ten FPGAs. The biggest problem with products based on FPGA design is system maintenance and upgrades. When upgrading an FPGA system, you must reconnect the download cable or use a pro...
