One embodiment relates to a data detection and event capture circuit. Data comparator logic receives a monitored data word from a parallel data bus and generates a plurality of pattern detected signals. Any pattern detection logic receives the plurality of pattern detected signals and generates a plurality of any pattern detected signals. Sequence detection logic receives the plurality of pattern detected signals and generates a plurality of sequence detected signals. Another embodiment relates to a method of data detection and event capture. Another embodiment relates to an integrated circuit having a first data detection and event capture circuit in a receiver circuit and a second data detection and event capture circuit in a transmitter circuit. Other embodiments and features are also disclosed.

Method and apparatus for data detection and event capture

An integrated circuit includes a control circuit, a first-in first-out circuit, and a serializer circuit. The control circuit generates parallel pulse-width modulation data in first parallel pulse-width modulation signals. The first-in first-out circuit stores the parallel pulse-width modulation data indicated by the first parallel pulse-width modulation signals. The first-in first-out circuit outputs the stored parallel pulse-width modulation data in second parallel pulse-width modulation signals. The serializer circuit converts the parallel pulse-width modulation data indicated by the second parallel pulse-width modulation signals to serial pulse-width modulation data in a serial pulse-width modulation signal.
