Abstract: A method and system includes generating a cache entry comprising cache line data for a plurality of cache clients and receiving a cache invalidate instruction from a first of the plurality of cache clients. In response to the cache invalidate instruction, the data valid/invalid state is changed for the first cache client to an invalid state without modifying the data valid/invalid state for the other of the plurality of cache clients from the valid state. A read instruction may be received from a second of the plurality of cache clients and in response to the read instruction, a value stored in the cache line data is returned to the second cache client while the data valid/invalid state for the first cache client is in the invalid state and the data valid/invalid state for the second cache client is in the valid state.
