Universal reconfigurable logic.

<p>By connecting the output of AHaH nodes (circles) to the input of static NAND gates, one may create a universal reconfigurable logic gate by configuring the AHaH node attractor states (). The structure of the data stream on binary encoded channels and support AHaH attractor states (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0085175#pone-0085175-g002" target="_blank">Figure 2</a>). Through configuration of node attractor states the logic function of the circuit can be configured and all logic functions are possible. If inputs are represented as a spike encoding over four channels then AHaH node attractor states can attain all logic functions without the use of NAND gates.</p>
