20130254488 | SYSTEM AND METHOD FOR SIMPLIFYING CACHE COHERENCE USING MULTIPLE WRITE POLICIES - System and methods for cache coherence in a multi-core processing environment having a local/shared cache hierarchy. The system includes multiple processor cores, a main memory, and a local cache memory associated with each core for storing cache lines accessible only by the associated core. Cache lines are classified as either private or shared. A shared cache memory is coupled to the local cache memories and main memory for storing cache lines. The cores follow a write-back to the local memory for private cache lines, and a write-through to the shared memory for shared cache lines. Shared cache lines in local cache memory enter a transient dirty state when written by the core. Shared cache lines transition from a transient dirty to a valid state with a self-initiated write-through to the shared memory. The write-through to shared memory can include only data that was modified in the transient dirty state. | 09-26-2013 |
20150143046 | SYSTEMS AND METHODS FOR REDUCING FIRST LEVEL CACHE ENERGY BY ELIMINATING CACHE ADDRESS TAGS - Methods and systems which, for example, reduce energy usage in cache memories are described. Cache location information regarding the location of cachelines which are stored in a tracked portion of a memory hierarchy is stored in a cache location table. Address tags are stored with corresponding location information in the cache location table to associate the address tag with the cacheline and its cache location information. When a cacheline is moved to a new location in the memory hierarchy, the cache location table is updated so that the cache location information indicates where the cacheline is located within the memory hierarchy. | 05-21-2015 |
20150143047 | SYSTEMS AND METHODS FOR DIRECT DATA ACCESS IN MULTI-LEVEL CACHE MEMORY HIERARCHIES - Methods and systems for in direct data access in, e.g., multi-level cache memory systems are described. A cache memory system includes a cache location buffer configured to store cache location entries, wherein each cache location entry includes an address tag and a cache location table which are associated with a respective cacheline stored in a cache memory. The system also includes a first cache memory configured to store cachelines, each cacheline having data and an identity of a corresponding cache location entry in the cache location buffer, and a second cache memory configured to store cachelines, each cacheline having data and an identity of a corresponding cache location entry in the cache location buffer. Responsive to a memory access request for a cacheline, the cache location buffer generates access information using one of the cache location tables which enables access to the cacheline without performing a tag comparison at the one of the first and second cache memories. | 05-21-2015 |
20150347297 | SYSTEMS AND METHODS FOR IMPLEMENTING A TAG-LESS SHARED CACHE AND A LARGER BACKING CACHE - A computer processing system includes a plurality of nodes, each node having at least one processor core and at least one level of cache memory which is private to the node, a shared, last level cache (LLC) memory device and a shared, last level cache location buffer containing cache location entries, each cache location entry storing an address tag and a plurality of location information. The location information stored in a cache location entry points to an identified cacheline location within the LLC that stores a cacheline associated with the location information. The cacheline stored in the LLC has associated information identifying the cache location entry. | 12-03-2015 |
20150347302 | MANAGEMENT OF SHARED PIPELINE RESOURCE USAGE BASED ON LEVEL INFORMATION - The execution or processing of an application can be adapted or modified based on a level of a cache in which a requested data block resides, by extracting level information from a cache hierarchy. When a request for a data block is made by a core to a cache memory system, the cache memory system extracts a level of a cache memory in which the data block resides from information stored in the cache memory system. The core is informed of the level of the cache memory in which the data block resides, and uses this information to adapt its processing of the application. | 12-03-2015 |
