Abstract
Official abstract text for this publication.
A tracking buffer apparatus is disclosed. A tracking buffer apparatus includes lookup logic configured to locate entries having a transaction identifier corresponding to a received request. The lookup logic is configured to determine which of the entries having the same transaction identifier has a highest priority and thus cause a corresponding entry from a data buffer to be provided. When information is written into the tracking buffer, write logic writes a corresponding transaction identifier to the first free entry. The write logic also writes priority information in the entry based on other entries having the same transaction identifier. The entry currently being written may be assigned a lower priority than all other entries having the same transaction identifier. The priority information for entries having a common transaction identifier with one currently being read are updated responsive to the read operation.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus comprising: a tracking buffer having N entries, wherein each entry includes a transaction identifier to identify a transaction, and an order identifier to identify a priority order within a particular transaction having a corresponding transaction identifier, wherein the tracking buffer is configured to store a same transaction identifier in multiple ones of the N entries; and lookup logic configured to, responsive to receiving a request that…
