    Autosophy is a new science which tries to explain self-assembling structures, such as crystals or living trees, in mathematical terms. This research provides algorithms for growing self-learning data networks in memories, similar to the growing of data crystals or data trees, without programming or conventional data processing. The new learning algorithms provide an entirely new technology for bui... View full abstract»

    A FIFO (First-in, First-Out memory device) can be thought of as a “passthrough window” between two independently-clocked digital subsystems-each marching to its own drummer, as it were. To adequately perform this role in practical digital systems, FIFOs are “schizoid”: they are memory devices, and they also are logic-synchronization circuits. Increasingly, newer FIFOs have ...
