Abstract: Systems, methods, devices, circuits for data processing, and more particularly to data processing including operational marginalization capability. In one case a data processing system is disclosed that includes a loop detector circuit and a sample based noise injection circuit. The loop detector circuit applies a loop detection algorithm to a data input to yield a loop detected output, and the sample based noise injection circuit generates a noise component based at least in part on the loop detected output.

Abstract: Techniques are provided for automatic gain control loop adaptation in circuitry for processing such data signals. In one example, an apparatus comprises read channel circuitry and signal processing circuitry associated with the read channel circuitry. The signal processing circuitry comprises an amplifier, a detector operatively coupled to the amplifier, and a feedback path operatively coupled between the detector and the amplifier. The amplifier is configured to receive and amplify an input signal received by the read channel circuitry. The detector is configured to detect a data pattern from the amplified input signal. The feedback path is configured to provide a feedback signal to the amplifier to adjust a gain of the amplifier, and to generate the feedback signal in accordance with a value selected to improve detection of the data pattern by increasing an amplitude of the data pattern around a given frequency.
