Hardware, Embedded Systems "A computer chip that performs calculations using probabilities, instead of binary logic, could accelerate everything from online banking systems to the flash memory in smart phones and other gadgets. Rewriting some fundamental features of computer chips, Lyric Semiconductor has unveiled its first "probability processor," a silicon chip that computes with electrical signals that represent chances, not digital 1s and 0s."

Based on pulse stream arithmetic?

It doesn't really say how they're doing this. Some commentors seem to assume that it is based on analog systems, but I wonder weather it may be based on pulse stream arithmetic.

The company says that the cell function is derived from the characteristics of single devices. That implies analog.

If you look inside a modern CPU or memory chip you'll find that they are often using non-rail-to-rail or "pulsed" logic signals. High performance ALU's are generally implemented using dynamic circuits, which operate in a sort of "pulsed" way, memories use reduced voltage swing to increase readout speed and lower power etc. That's also a form of analog circuitry, although used in otherwise digital IC's. These techniques don't scale well so general purpose digital functions are standard cell based.
