摘要： Methods, apparatuses, and computer program products are disclosed for cache management. Embodiments include receiving, by a cache controller, a request to insert a new cache line into a cache; determining, by the cache controller, whether the new cache line is associated with a forced injection; in response to determining that the new cache line is associated with a forced injection, accepting, by the cache controller, the insertion of the new cache line into the cache; and in response to determining that the new cache line is not associated with a forced injection, determining, by the cache controller, whether to accept the insertion of the new cache line based on a comparison of an address of the new cache line to a predefined range of addresses.
