ABSTRACT:
A rule based processing system that is optimized for implementation in hardware. The system includes a set of logic gates that are used to implement a rule network connected to a working memory composed from a set of memory components. When a set of inputs are presented to the logic gates, a set of inferences are formed and the results are stored in the memory components. The inferences that are stored in the working memory are used to determine the state of the system at any given time. These inferences can be output to an external device to report on the status of the system. The rule based production system is designed to be implementable on a high performance semiconductor micro-chip and is thus suitable for use in embedded real-time applications.
