Abstract: A command is received from a host. It is determined which paths in a plurality of paths are enabled. The type of command and the length associated with the command, if applicable, are determined. A path to use to perform the command is selected from the plurality of paths based at least in part on (1) which paths are determined to be enabled and one or more of the following (2a) the type of the command or (2b) the length associated with the command. The selected path is used to perform the command.

Abstract: A method for recovering data is disclosed. A sensed analog signal is converted into digital samples using an analog-to-digital converter (ADC). The digital samples are processed into processed digital samples using a first filter. The processed digital samples are decoded into decoded data. Whether the decoded data is acceptable is then determined. The processed digital samples are fed back to the first filter using a reprocessing circuit such that the processed digital samples are reprocessed into reprocessed digital samples in the event that the decoded data is unacceptable. A set of reprocessing coefficients is provided for the first filter to reprocess the processed digital samples.
