1. A sequence generator comprising:
- a neural network responsive to input signals applied to a plurality of inputs that are internally connected to a cross-connect network, where said neural network develops a plurality of output signals responsive to said input signals and to interconnection values within said cross-connect network;
a delay/averaging network responsive to said plurality of output signals of said neural network, for developing a delayed plurality of output signals that are related to said plurality of output signals of said neural network; and
an input interconnection network responsive to said plurality of delayed output signals of said delay network for developing said plurality of input signals of said neural network;
WHEREthe interconnections within said cross-connect network develop specified local minima in the energy function describing the response of said neural network to said input signals, and said input interconnection network determines the sequence of neural network output signals developed by the sequence generator.

Abstract
A sequence generator employing a neural network having its output coupled to at least one plurality of delay elements. The delayed outputs are fed back to an input interconnection network, wherein they contribute to the next state transition through an appropriate combination of interconnections.
