Abstract
This invention discloses a system comprising a first comparator circuit configured to assert a first control signal in response to a first input number matching one of a first numbers stored therein, a second comparator circuit configured to assert a second control signal in response to: (i) at least one latched assertion of the first control signal; (ii) a second input number matching an intermediate number produced by incrementing the first input number; and (iii) an assertion of an input signal, and to de-assert the second control signal absent of either the matching between the second input number and the intermediate number or the de-assertion of the input signal, and a generator circuit configured to output a predetermined instruction data stored therein in response to the assertion of the first control signal, and to output a third number in response to the assertions of the second control signal.
