Example Embodiment

[0023] The present invention will now be further described in conjunction with the embodiments and drawings:

[0024] The present invention takes multiple digital receiving boards, one optical fiber processing board and PC as examples. The digital receiving board contains a Xilinx FPGA-k7160t and an external dedicated FLASH, the model is SPANSION S29GL512P, FPGA and FLASH are asynchronous read and write interfaces; the main components in the optical fiber processing board are a Xilinx FPGA-V6lx240t and a network interface chip 88e1111 ; Multiple digital receiving boards and optical fiber processing boards are interconnected by optical fibers, and the optical fiber processing boards and PCs communicate data through the network.

[0025] step one:

[0026] When the FPGA program of the digital receiving board needs to be updated, use the Xilinx tool IMPACT to convert the newly generated .bit file into a .bin file that can be burned into Flash. The file size is 0x53638C*8bit (depending ...

Abstract

The present invention designs a multi-board FPGA program programming system and method based on network and optical fiber data transmission. Multiple digital receiving boards are connected to optical fiber processing boards through optical fibers, and the optical fiber processing boards communicate with PCs through network interfaces. The PC transmits the program to be updated to the optical fiber processing board through the network interface, and the optical fiber processing board uses the optical fiber to transmit the program to multiple digital receiving boards at the same time. Programming of FPGA programs for multiple boards.

Description

technical field [0001] The invention belongs to the field of digital intermediate frequency reception in array radar signal processing, and relates to programming of multi-board FPGA programs. When the multi-board FPGA program needs to be modified, the invention uses the network interface and the optical fiber interface to upload the program to be updated from the PC to the multi-piece FPGA board, so as to realize simultaneous programming of the multi-board FPGA program. Background technique [0002] With the development of large-scale phased array radar and the emergence of thousands of array element radars, the number of digital receiving unit boards in radar signal processing continues to increase. The boards have the same structure and use the same FPGA program. In the traditional radar debugging Among them, the FPGA program of the digital receiving board often needs to be modified and updated. When the FPGA program is modified and updated, it is necessary to program the...
