Patent ID: 7275124

Claim:
A method comprising: monitoring at a bus interface a number of requests of a particular type for access to a resource, each request of the particular type requiring one data buffer of a number of data buffers for the particular request type at the bus interface, wherein the request of the particular type comprises a read transaction with a snoop response of modified intervention, the modified intervention indicating that a processor coupled to the bus interface has a line of memory modified in its cache that the processor wishes to provide to a requesting master initiating the read transaction, each snoop response with modified intervention requiring one modified intervention data buffer of multiple modified intervention data buffers at the bus interface for buffering modified intervention read data; and responsive to a received request of the particular type, initiating an override signal at the bus interface to terminate a received snoop response of modified intervention when a monitored number of read transactions with snoop responses of modified intervention exceeds the number of modified intervention data buffers at the bus interface.
