A computing system includes: a fetch block configured to provide an initial destination and a way prediction associated with the initial destination for accessing a retrieval target; a way block, coupled to the fetch block, configured to determine a way-fetch result based on the way prediction; a parallel circuit, coupled to the fetch block, configured to determine an access destination based on the initial destination in parallel and concurrently with the way block; and an access block, coupled to the way block and the parallel circuit, configured to access the retrieval target based on comparing the access destination and the way-fetch result.
