Abstract
A microprocessor comprises a cache including a tag array; a tagpipe that arbitrates access to the tag array; and a logic analyzer for investigating a starvation, livelock, or deadlock condition. The logic analyzer, which comprises read logic coupled to the tagpipe, is configured to record snapshots of transactions to access the tag array.
