Modulus The number of states through which a counter sequences before repeating. Modulo- n (or mod- n ) counter A counter with a modulus of n. Memory section A set of ﬂip-ﬂops in a synchronous circuit that hold its present state. Maximum modulus (m max ) The largest number of counter states that can be represented by n bits (m max 2 n )

(Left is deﬁned in MAX PLUS II as toward the MSB.) Left shift A movement of data from the right to the left in a shift register.

Johnson counter A serial shift register with complemented feedback from the output of the last ﬂip-ﬂop to the input of the ﬁrst. GENERIC A clause in the entity declaration of a VHDL component that lists the parameters that can be speciﬁed when the component is instantiated. Count sequence The speciﬁc series of output states through which a counter progresses.Ĭounter A sequential digital circuit whose output progresses in a predictable repeating pattern, advancing by one state for each clock pulse.Ĭount-sequence table A list of counter states in the order of the count sequence.ĭataﬂow design A VHDL design technique that uses Boolean equations to deﬁne relationships between inputs and outputs.ĭOWN counter A counter with a descending sequence.Įxcitation table A table showing the required input conditions for every possible transition of a ﬂip-ﬂop output.įull-sequence counter A counter whose modulus is the same as its maximum modulus ( m 2 n for an n-bit counter).
