Abstract
A data processing method includes receiving a read request or a write request with an address of data, checking a value of a counter indicator when a miss of the address is responded by the snoop filter, and snooping at least two of the clusters when the counter indicator presents a first outcome.
Claims14
A data processing method of a snoop filter for a plurality of clusters with caches comprising:
- receiving a read request or a write request with an address of data;
- checking a value of a counter indicator when a miss of the address is responded by the snoop filter;
- and
- snooping at least two of the clusters when the counter indicator presents a first outcome.

A data processing method of a snoop filter for a cache in a plurality of clusters comprising:
- receiving an allocating request;
- checking a counter indicator when a tag of the snoop filter is full;
- and
- allocating a cache line of the snoop filter by invalidating data in the cache when the counter indicator is greater than a threshold.

A data processing method of a snoop filter for a cache in a plurality of clusters, comprising:
- receiving a de-allocating request with an address;
- checking a counter indicator when a miss of the address is responded by the snoop filter;
- and
- decreasing the counter indicator value by one when the counter indicator is greater than zero.
