Abstract: The interface for inter-thread communication between a plurality of threads including a number of producer threads for producing data objects and a number of consumer threads for consuming the produced data objects includes a specifier and a provider. The specifier is configured to specify a certain relationship between a certain producer thread of the number of producer threads which is adapted to produce a certain data object and a consumer thread of the number of consumer threads which is adapted to consume the produced certain data object. Further, the provider is configured to provide direct cache line injection of a cache line of the produced certain data object to a cache allocated to the certain consumer thread related to the certain producer thread by the specified certain relationship.

Abstract: A method for managing objects stored in a cache memory of a processing unit. The cache memory includes a set of entries corresponding to an object. The method includes: checking, for each entry of at least a subset of entries of the set of entries of the cache memory, whether an object corresponding to each entry includes one or more references to one or more other objects stored in the cache memory and storing the references; determining among the objects stored in the cache memory, which objects are not referenced by other objects, based on the stored references; marking entries as checked to distinguish entries corresponding to objects determined as being not referenced from other entries of the checked entries, and casting out, according to the marking, entries corresponding to objects determined as being not referenced.
