use such a device as a random number generator whose bits would then be fed into a set of stochastic logic circuits. In such a system, values would be represented as probabilities—4 would be represented by a seemingly random string of say 100 bits, of which about 40 would be 1s. It’s easy to see that stochastic computing would be relatively immune to simple errors where a bit or two gets flipped, because it would hardly make a difference. But it also makes some calculations less complex. Multiplying two numbers, for example, can simply be done with a single AND gate. I found this as clear as mud. Are the random strings always the same or are they different each time (derived from some stochastic process which always has the same probability of 40/100)?
