Abstract

The invention discloses an FPGA (field programmable gate array) remote update device which comprises an FPGA module, an embedded processor remote update system is arranged in the FPGA and comprises a communication module and a remote update module, the communication module is connected with an upper computer and the remote update module, and the remote update module is connected with a configuration FLASH through the FPGA module. The invention further discloses an FPGA remote update method. The method includes that S01, the upper computer sends an agreed program update instruction to the embedded processor remote update system, and the remote update module collects states of the update system to determine whether to receive the update instruction or not; S02, if update is allowed, the upper computer issues a data frame and sends the data frame to the remote update module for temporary storage of the data frame and completes update of the data frame according to specific timing of the configuration FLASH. The FPGA remote update device and method has the advantages of simpleness in principle, convenience in operation, low cost and the like.

Description

technical field [0001] The invention mainly relates to the technical field of programmable logic devices, in particular to an FPGA remote update device and method. Background technique [0002] At present, programmable logic device FPGA is widely used in industry for data acquisition, communication and control. In the process of research and development, mass production and testing, the update of FPGA logic programs will be involved. Most of the existing remote updates use third-party controllers: for example, a piece of DSP or a piece of CPLD or FPGA to update the FPGA that needs to be upgraded. The current papers or patents related to this are: [0003] Thesis 1 "Design and Implementation of Remote Update Based on NiosII Multi-chip FPGA": This paper highlights a design method based on NiosII multi-chip FPGA remote update, which realizes the update of FPGA configuration files through Ethernet port and serial port. The design and implementation scheme, hardware design and...
