VLSI design of a high speed soft decision Viterbi detector

摘要

Summary form only given. The design of a Viterbi detector for highspeed disk drive channels is presented. The detector is a soft decisiondetector that operates on a time varying trellis based on a matchedspectral null code. The design was developed by creating a high-levelmodel of the system to resolve high-level design issues. Standard designtools were used for logic simulation and layout generation. The designhas been fabricated and verified to be fully functional
