[0025] Aiming at the shortcomings of the prior art, the present invention overcomes the defects that the traditional FPGA configuration circuit can only detect errors generated during code stream transmission, cannot locate errors, and cannot correct errors, and proposes a code stream correction The single-event hardened FPGA configuration circuit with error detection function will be described in detail below with reference to the drawings.
[0026] Such as image 3 As shown, the configuration circuit of the present invention includes a general interface circuit, a JTAG interface circuit, a bus interface circuit, a configuration bus, a configuration register, a coding error correction circuit, a configuration state machine, and a configuration memory array. The bus interface circuit is connected to the configuration bus, one or Multiple external communication interface circuits (including JTAG interface circuits and general interface circuits), multiple configuration registers ar...
