Field programmable gate array device dead-weight configuration device and method

Abstract

The invention relates to a field programmable gate array (FPGA) device dead-weight configuration device and method. The FPGA device dead-weight configuration device comprises a self configuration circuit which is arranged in a FPGA device and a signal processing circuit which is arranged at the outer portion of the FPGA device. The self configuration circuit comprises a first counter, a second counter, a third counter and a detection circuit, wherein the first counter, the second counter and the third counter are used for receiving the same clock pulse signal to fix time and a low level signal is output when the fixed time reaches a preset value. One of the counters is detected whether the one is different from the other two in output by the detection circuit, the low level signal is output when the one is different from the other two in the output, and a level signal the same with the first counter, the second counter and the third counter is output when the one is the same with the other two in the output. An output end of the detection circuit is connected with the signal processing circuit which transmits the low level signal output by the detection circuit to a reconfiguration pin and controls the reconfiguration pin to keep time of low level above preset time. The FPGA device dead-weight configuration device and method has the advantages of being few in needed external devices, simple in structure and few in occupied printed circuit board (PCB) resources.

Description

technical field [0001] The present application relates to the field of space instrument engineering, in particular to a self-weight configuration device and method of a field programmable gate array device. Background technique [0002] With the development of aerospace technology and the needs of various fields, more and more satellites and spacecraft have been put into use. The functions of spacecraft in orbit are becoming more and more complex, which requires complex logic to achieve more functions. Large-scale Field-Programmable Gate Array (Field-Programmable Gate Array, FPGA device) is an ideal device, especially SRAM (Static Random Access Memory, static random access memory) type FPGA device has the advantages of large scale, strong function, reprogrammable and so on. Currently, SRAM-type FPGA devices are widely used in the commercial field. Since there are various particles in the space environment, such as protons, electrons, alpha particles, heavy ions, gamma rays...
