Problems solved by technology

[0002] When the FPGA configuration files and coefficient files corresponding to a large number of sub-arrays on the phased array radar array need to be updated, if you use the traditional JTAG download cable to program one by one, it will waste a lot of time. If you want to update all sub-arrays at the same time The configuration file can be done with the help of SPI FLASH programming method based on FPGA programming
[0003] The data files and configuration files used by the FPGA can usually be stored in its external FLASH, and these files generally need to be programmed through the JTAG download cable one piece of FLASH at a time; the existing batch programming SPIFLASH technology, there are many Problem: Either an additional programming system needs to be built; or a card socket is used to connect the FLASH, and installation and disassembly are required before and after programming

Abstract

The invention relates to an SPI (Serial Peripheral Interface) FLASH programming method based on FPGA (Field Programmable Gate Array) programming, and aims to solve the problems that data files and configuration files used by an existing FPGA are usually stored in plug-in FLASH, and the files need to be programmed through a JTAG (Joint Test Action Group) downloading cable, so that the time consumption is long, and the operation is difficult. According to the invention, the programming and verification of the coefficient and the configuration file of the plug-in SPI FLASH are realized through the program code embedded in the FPGA. On an existing phased array radar platform, extra system resources are not needed, and large-batch programming and verification of coefficients and configuration files of the plug-in SPI FLASH are achieved through program codes embedded in the FPGA.

Description

technical field [0001] The invention belongs to the technical field of radar, and relates to an SPI FLASH programming method based on FPGA programming, which is applied when a large amount of SPI FLASH needs to be simultaneously programmed on a phased array radar array. Background technique [0002] When the FPGA configuration files and coefficient files corresponding to a large number of sub-arrays on the phased array radar array need to be updated, if you use the traditional JTAG download cable to program one by one, it will waste a lot of time. If you want to update all sub-arrays at the same time The configuration file can be done by using the SPI FLASH programming method based on FPGA programming. [0003] The data files and configuration files used by the FPGA can usually be stored in its external FLASH, and these files generally need to be programmed through the JTAG download cable one piece of FLASH at a time; there are many existing technologies for batch programmin...
