Abstract: A fault-tolerant system including a calculation unit and an output synthesizer is provided. The calculation unit receives a first environmental parameter and input data, wherein the calculation unit further includes a first and a second calculation circuits. The first calculation circuit is arranged to perform a calculation on the input data in response to the first environmental parameter to generate a first calculation result. The second calculation circuit is different from the first calculation circuit, and arranged to perform the calculation on the input data in response to the first environmental parameter to generate a second calculation result. The output synthesizer selects a first and a second set of bits from the first and the second calculation result according to a control signal, and synthesizes the first set of bits and the second set of bits in sequence to generate an adjusted calculation result.
