Error Immune Logic for Low-Power Probabilistic Computing
Figure 1
The effect of a single-bit error or bit flip on the inputs of an NAND function and XOR function is shown. Note that if the new input combination resulting from a bit flip maps to the same output as the input combo with no bit flip, no error is seen at the output. A NAND function is much less likely to propagate an input bit flip to the output resulting in an error than an XOR function. (a) NAND function (b) XOR function.
