A fpga-based anti-radiation data processing system and method

Abstract

The invention discloses an FPGA-based anti-radiation data processing system and method, including a commercial SRAM structure FPGA with dual-port RAM, which can be used for data processing boards in harsh environments such as radiation. The data processing board includes two anti-radiation anti-fuse Aeroflex UT6235FPGAs, two non-complete anti-radiation Xilinx Virtex-5FX130T FPGAs and related storage and interface peripheral chips. Each Xilinx FPGA includes three parts: the control and processing part; the first data processing module, which is used for input data processing and stores the data processing results in the first part of the dual-port RAM; and the first data processing module The same second data processing module performs the same processing on the same input data, and the data processing result is stored in the second part of the dual-port RAM. The control and processing module compares the processing results of the two processing modules, and if they are consistent, the processing results are stored in a designated memory. If inconsistent, re-process.

Description

Technical field: [0001] The invention relates to an FPGA-based data processing board, in particular to an FPGA-based anti-radiation high-performance data processing system and method. Background technique: [0002] With the development of new high-resolution and active remote sensing instruments, in applications such as spaceborne or aerial remote sensing, a high-performance data processing system is required to process the data acquired by the instrument in real time or near real time to reduce the amount of stored or downloaded data. [0003] In applications such as these, the working environment is harsh, with radiation such as high-energy particles, cosmic rays, and solar soft X-rays, which can cause failure and damage to electronic devices. Therefore, it is necessary to enhance the anti-radiation capability of electronic devices to reduce or prevent the occurrence of such events. Radiation refers to the damage to the processing system caused by electromagnetic waves su...
