A data flow implementation of a virtual machine.
At this point it is a collection of gate-level logics implemented as Pure Data abstractions. More complex logics are built on-top of small ones creating the whole logic circuit layer of a computing machine.
Shown above is a 1-bit binary adder logic circuit, Where A and B are operands, Ci is the immediate carry, Ci+1 is the next carry, and S is the sum of A + B.
