Abstract

The invention provides an FPGA-based embedded device online configuration method and system. The method and the system are high in adaptability; an upper computer can use devices such as a computer, a set-top box and the like, and supports multiple operation systems of Window, Linux, Android and the like; the realization is quick and convenient, and driver and control programs in the upper computer do not need to be developed; embedded devices connected in series are supported to be subjected to firmware updating, and each device can be updated to programs with different versions; all the embedded devices are subjected to online dynamic firmware updating, without influencing operations which are being carried out; remote firmware updating can be realized, so that technical staffs do not need to arrive at the scene; and the remote firmware updating process can be controlled in a script writing manner, so that the efficiency is further improved.

Description

technical field [0001] The invention relates to the field of software, in particular to an online configuration method and system for embedded devices based on FPGA. Background technique [0002] FPGA (Field-Programmable Gate Array), that is, field programmable gate array, is a product of further development on the basis of programmable devices such as PAL, GAL, and CPLD. It emerged as a semi-custom circuit in the field of application-specific integrated circuits (ASIC), which not only solves the shortcomings of custom circuits, but also overcomes the shortcomings of the limited number of original programmable device gates. [0003] The development of FPGA is very different from the development of traditional PC and single-chip microcomputer. FPGA is mainly based on parallel computing, which is realized by hardware description language; compared with the sequential operation of PC or single-chip microcomputer (whether it is von Neumann structure or Harvard structure), there...
