Sequence Detector A Sequence Detector is a digital circuit designed to detect a specific pattern of bits in a serial input stream. This project demonstrates the design and implementation of a sequence detector using Verilog, showcasing its application in communication systems, error detection, and control logic.
Features Pattern Recognition: Detects a predefined sequence of bits in a serial input. Configurable Patterns: Easy to modify for different bit sequences. Overlapping Sequences: Supports detection of overlapping patterns in the input stream. Synchronous Design: Operates in sync with the clock signal for reliable detection. Project Highlights Inputs:
Serial Input: The stream of bits to be monitored. Clock: Synchronizes the sequence detection process. Reset: Resets the detector to its initial state. Output:
Detection Signal: Indicates when the desired sequence is detected in the input stream. Operation Modes:
Non-Overlapping Mode: Detects the sequence without considering overlapping patterns. Overlapping Mode: Detects the sequence even when it overlaps with previously detected patterns. Workflow Initialization: The detector starts in the initial state upon reset. Pattern Matching: Monitors the serial input bit-by-bit. Transitions through states based on the incoming bits and the desired pattern. Sequence Detection: Activates the detection signal when the entire pattern is matched.
