New Chip Calculates with Probabilities in Hardware

Lyric's Error Correction Chip for Flash Memory Lyric Semiconductor

Most people with even the most fundamental knowledge of how computer chips work are familiar with binary logic — the system of ones and zeros that enable modern computing to occur — in which an input always results in a solid result (either a one or a zero). Now, a Boston-based startup is rewiring the basic concept of computation with a probability processor that deals in chance rather than binary logic, creating a chip that could speed all kinds of processes from flash memory in smartphones to better decision-making software for machines.
Lyric Semiconductor’s chip accepts probabilities as inputs instead of ones and zeros, and the output is also a probability — the odds that the two input probabilities match up. Rather than the usual NAND gates characteristic of conventional transistor schemes, the chips employ what are known as Bayesian NAND gates, named for the statistician Thomas Bayes whose field of thought is the basis for the idea.
I dug up some more and found about who this mathematician was from Britannica. Fortunately I was able to interpret what these people are trying to do. I found some thing really interesting. I found that in our Bharteya(Indian) Hindu scriptures, the magnifificent अथर्ववेदः (Atharvaveda) contains the theory of Probability and Discrete Mathematics also. This includes a kind of Boolean algebra(सामजस) and other abstract mathematics (विरल गणित) that discretized the functions of each of the operators and some times the complete number system itself, such as irrational algebra. Possibly I would suggest that there must be some mysterious but certain link between the Bayesian idea and our Vedas. I would also suggest that the later might be the source after all.
