Abstract
Official abstract text for this publication.
Methods and apparatus are provided for reusing snoop responses and data phase results in a cache controller. A cache controller receives a broadcast combined snoop response from a bus controller, wherein the broadcast combined snoop response corresponds to an incoming bus transaction BTR1 corresponding to a cache transaction CTR1 for an entry in at least one cache and wherein the combined snoop response is a combination of at least one snoop response from a plurality of cache controllers; receives broadcast cache line data from a source cache as instructed by the bus controller for the entry during a data phase; and processes a subsequent cache transaction CTR2 for the entry based on one or more of the broadcast combined snoop response and the broadcast cache line data.
First claim
Opening claim text (preview).
We claim: 1. A method, comprising: receiving a broadcast combined snoop response and at least one sideband signal from a bus controller, wherein said broadcast combined snoop response corresponds to an incoming bus transaction BTR1 corresponding to a cache transaction CTR1 for an entry in at least one cache and wherein said combined snoop response is a combination of at least one snoop response from a plurality of cache controllers, wherein said bus controller broadcasts said broa…
