Abstract
Pseudorandom values are produced using a memory and an arithmetic logic unit. The previous value is shifted four places to the left to form a shifted value. Next, the previous value is subtracted from this shifted value to form a subtracted value. The least significant bit of this subtracted value is complemented to form the new value.
