Abstract
Cache lines are identified that provide incorrect data for read requests. The cache lines are invalidated before the incorrect data causes processing failure conditions. The cache lines providing incorrect data may be detected according to a number of the same read requests to the same cache lines. The cache lines may also be identified according to an amount of time between the same read requests to the same cache lines. The same read requests to the same cache lines may be identified according to associated start addresses and address lengths.
