Abstract:
1. A system for path finding and terrain analysis the system comprising: at least one processing unit; a graph processing unit; an artificial intelligence logic unit; a local bus coupled to the at least one processing unit, the graph processing unit, the artificial intelligence unit and a bus interface unit; and a memory bus coupled to said bus interface unit, the at least one processing unit, a data memory, and a program memory; the graph processing unit further including: a network of interconnected nodes, each of said nodes having at least one digitally programmable delay unit; wherein each of said nodes of said graph processing unit further comprises: a plurality of input latches, each of the input latches being coupled to a respective input signal; a plurality of comparators, each of the comparators coupled to a respective output signal; transition detector operable to detect a transition in at least one of the outputs of said plurality of input latches, and further operable to assert a transition indication signal; at least one storage unit operable to store a plurality of edge weights, each of the edge weights corresponding to a respective comparator from said plurality of comparators; and at least one counter coupled to each of said plurality of comparators.
