Abstract

There is provided a method of processing a request to a rule by the use of an input signal, compressed rule information, and an output signal, comprising the steps of: representing said input signal as a plurality of two-bit pairs each pair corresponding to a variable in said input signal, representing the rule information with at least a first and second type of terms. The terms of said first type are each binary words, and each represents one allowable combination of the variables. And each term of said second type is a plurality of two-bit pairs and represents at least two allowable combinations of the variables. The method further comprises the step of testing whether there is a first type of match between at least one of said first terms and said input signal, testing whether there is a second type of match between at least one of said second terms and said input signal, generating an output signal as a plurality of two-bit pairs, each pair corresponding to a variable in said input signal, updating said output signal according to the following strategy: if there is a match of said first type, then the output signal is updated with values which are responsive to at least one of said first type of terms. And if there is a match of said second type, then the output signal is updated with values which are responsive to at least one of said second type of terms.
