Parallel computing
Parallel computing is a form of computation in which many calculations are carried out simultaneously, operating on the principle that large problems can often be divided into smaller ones, which are then solved concurrently . There are several different forms of parallel computing: bit-level,...

Necessity for a nano brain

Computing in the 20th century was confined inside a box, or machine, called computer or supercomputer; now, several parameters around us compute, the computing has left the box stretching into the world at large. Earlier, we used to have small amount of information stored in a book or server, and we used to upload and download as required. In this and to the next century, this could reverse, since, where we store information is becoming astronomically large. We need to extend computing beyond serial logic, as we did in the last century, if we dont, we could get isolated in the information domain, without getting connected to the desired point. Human brain follows pattern based computing

 increment of information generates a serious challenge for command, control and processing when connectivity among these information also increases exponentially. Since software uses a sequential approach to analyze connectivity, to shrink infinite complexity into a finite limit, mechanism of processing infinite information has to be embedded inside the hardware. Nano brain is such a device that physically addresses nearly infinite possible connections in seconds, alleviating the singularity in the software. This concept has the potential to solve at least three bottlenecks of human civilization, providing necessary intelligence

. The functional principle of a nano brain architecture is to exhibit “one-to-many communication at a time” among the constituent decision making units. By conventional circuit theory, it is parallel circuiting of elements. Since the conformation of wireing path changes along with electronic charge transport in the circuit, equivalent circuit would change continuously. The possible combination of such circuits is astronomically large therefore instead of defining a function for an evolving equivalent circuit, the concept of cellular automaton

 has been introduced. In addition, due to spherical design, information spreads out from the center of the sphere and again reflects back to the center from the outer surface. Every single atom in the spherical nano-brain experiences a continuous interference of feed forward information wave. Thus, the concept of circuit is violated here as collective evolution of a potential distribution in a 3 D space at a time can not be represented as a linear sequence of events in discrete times.

 in Human brain evolves continuously during entire life period, it gains folds. There are several attempts to realize evolutionary circuits, however majority of these attempts assemble a few static circuits and choose one of them during computation. Human brain's evolution is functionally different, neurons change connection to make short-route, these routes lead to faster decision making, we call it increasing efficiency through learning. A nano-brain changes connection between different sub-processors in a very similar fashion, therefore it learns with experience, since no hardware restriction is imposed in the nano-brain, possibilities of changing is enormously large, not astronomical since restriction due to resource limitation imposes an upper limit, however, that number of possibility ranges in the order of millions compared to tens in the present evolving hardwares.

then number of cells decreases in every layer as computation transits upward. The embedded cellular automaton cluster that represent entire nano brain, follows two different classes of cellular automaton rules. First class of rules are those which are followed in the cellular automaton grid, and the other class of rules are basically the transition rules between two cellular automaton layers, each layers are termed as sub-processors.
