What is a sequence detector?

What is a sequence detector?

A sequence detector is a sequential state machine that takes an input string of bits and generates an output 1 whenever the target sequence has been detected. In a Mealy machine, output depends on the present state and the external input (x).

What is sequence detector in Verilog?

A very common example of an FSM is that of a sequence detector where the hardware design is expected to detect when a fixed pattern is seen in a stream of binary bits that are input to it.

What is Moore FSM sequence detector?

A sequence detector is a sequential state machine. In a Moore machine, output depends only on the present state and not dependent on the input (x). Hence in the diagram, the output is written with the states.

What is a Moore sequence Detector?

Is this the sixth post in the sequence detectors design series?

Hi, this is the sixth post of the sequence detectors design series. The previous posts can be found here: sequence 1010, sequence 1011, sequence 1001, sequence 101, and sequence 110. I am going to cover both the Moore machine and Mealy machine in overlapping and non-overlapping cases.

How to design a non-overlapping 101 mealy sequence detector?

In this post, we’ll discuss the design procedure for non-overlapping 101 Mealy sequence detectors. The steps to design a non-overlapping 101 Mealy sequence detectors are: Rule 1 : States having the same next states for a given input condition should have adjacent assignments.

What is the output of a sequence detector?

sequence detector accepts as input astring of bits: either 0 or 1. Its output goes to 1 when a target sequence has been detected. There are two basic types: overlapandnon-overlap. In an sequence detector that allows overlap, the final bits of one sequence can bethe start of another sequence.

What is a mealy and Moore sequence detector?

Prerequisite – Mealy and Moore machines A sequence detector is a sequential state machine that takes an input string of bits and generates an output 1 whenever the target sequence has been detected. In a Mealy machine, output depends on the present state and the external input (x).
