Abstract
A system and method involving a read channel pipeline having a plurality of vector sequencers that may be used to control the processing blocks. In one embodiment, a read channel pipeline may include processing blocks that may be controlled a command word provided by vector sequencers. Incoming data may be delineated by identifying an early period, a steady-state period, and a trailing period. Instead of controlling these blocks with a static state machine controller, a plurality of vector sequencers are coupled to the plurality of processing blocks. Thus, a first vector sequencer may control the processing blocks during the early period and the steady state period, but then hand off control to a second vector sequencer for the trailing period. Using vector sequencers for implementing command words allows for greater programming flexibility once the device has been manufactured and deployed for use.
