Anti-radiation data processing system and method based on FPGA

Abstract

The invention discloses an anti-radiation data processing system and method based on an FPGA. The data processing system comprises a data processing card applicable to severe environments such as radiation environments and comprising the double-port RAM commercial SPAM structure FPGA. The data processing card comprises two pieces of anti-radiation antifuse Aeroflex UT6235FPGAs, two pieces of incomplete anti-radiation Xilinx Virtex-5FX130T FPGAs and relevant storages, interfaces and other peripheral chips. Each piece of Xilinx Virtex-5FX130T FPGA comprises three parts, namely a control and processing part, a first path data processing module used for processing input data and storing a data processing result into a first part of a double-port RAM and a second path data processing module identical with the first path data processing module and identically processing the same input data. A data processing result is stored into a second part of the double-port RAM. A control and processing module compares the processing results of the two path processing modules. If the results are identical, the processing results are stored into a designated storage and if the results are not identical, processing is repeated.

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...

Examples

Embodiment Construction

[0026] In applications such as data processing for aerospace instruments, the reliability requirements are not as high as in safety systems, so some reliability can be traded in exchange for increased processing power. It is an advantage to use commercially available not fully radiation hardened processing devices, even if some non-destructive errors, such as bit flips, can be corrected by correlation techniques. The technology involved in the present invention realizes the enhancement of the anti-radiation ability of commercial incomplete anti-radiation processing devices through design and software.

[0027] Many methods can be used to detect and correct such errors, but their application is limited by the amount of computation. The radiation resistance enhancement based on the processing flow design and software method can ensure that the data processed by the data processing system will not have large errors, and the key information of the original data can be obtained.
