Embodiment Construction
[0064] refer to figure 1 , a ground reconfigurable FIR filter parameter anti-single event flipping reinforcement method, including the following steps:
[0065] (1) Store the FIR filter parameters to be anti-radiation reinforcement in the dual-port Block RAM, the parameters stored in the dual-port Block RAM include the original FIR filter parameter Ai, the first copy Bi of Ai, the second copy of Ai Copy Ci, Ai, Bi, and Ci are respectively stored in different data bits in the same address of the dual-port Block RAM. The depth of is the number n of FIR filter parameters to be hardened against radiation;
[0066] (2) The parameter injection module on the ground generates the write address and data of the Block RAM according to the injection sequence and the injected parameters on the ground, and controls the port 1 write timing of the Block RAM, and writes the parameters injected on the ground into the Block RAM. Note that the parameter module has the highest writing priority; ...
