Title: Caching data from remote memories

Abstract

An approach is disclosed that caches distant memories within the storage a local node. The approach provides a memory caching infrastructure that supports virtual addressing by utilizing memory in the local node as a cache of distant memories for data granules. The data granules are accessed along with metadata and an ECC associated with the data granule. The metadata is updated to indicate storage of the selected data granule in the cache.

Compressing data for storage in cache memories in a hierarchy of cache memories

Patent Tomei, Matthew J.; Bedoukian, Philip B.; Das, Shomit N.

An electronic device includes at least one compression-decompression functional block and a hierarchy of cache memories with a first cache memory and a second cache memory. The at least one compression-decompression functional block receives data in an uncompressed state, compresses the data using one of a first compression or a second compression, and, after compressing the data, provides the data to the first cache memory for storage therein. When the data is retrieved from the first cache memory to be stored in the second cache memory, when the data is compressed using the first compression, the compression-decompression functional block decompressesmore » « less

Promoting prefetched data from a cache memory to registers in a processor

Patent Kotra, Jagadish; Kalamatianos, John

An electronic device includes a processor having a cache memory, a plurality of physical registers, and a promotion logic functional block. The promotion logic functional block promotes prefetched data from a portion of a cache block in the cache memory into a given physical register, the promoting including storing the prefetched data in the given physical register. Upon encountering a load micro-operation that loads data from the portion of the cache block into a destination physical register, the promotion logic functional block sets the processor so that the prefetched data stored in the given physical register is provided to micro-operationsmore » « less

Using predictions of outcomes of cache memory access requests for controlling whether a request generator sends memory access requests to a memory in parallel with cache memory access requests

Patent Yin, Jieming; Eckert, Yasuko; Poremba, Matthew R.; ...

An electronic device handles memory access requests for data in a memory. The electronic device includes a memory controller for the memory, a last-level cache memory, a request generator, and a predictor. The predictor determines a likelihood that a cache memory access request for data at a given address will hit in the last-level cache memory. Based on the likelihood, the predictor determines: whether a memory access request is to be sent by the request generator to the memory controller for the data in parallel with the cache memory access request being resolved in the last-level cache memory, and, whenmore » « less

Cache directory look-up re-use as conflict check mechanism for speculative memory requests

Patent Ohmacht, Martin

In a cache memory, energy and other efficiencies can be realized by saving a result of a cache directory lookup for sequential accesses to a same memory address. Where the cache is a point of coherence for speculative execution in a multiprocessor system, with directory lookups serving as the point of conflict detection, such saving becomes particularly advantageous.

Bit error protection in cache memories

Patent Kalamatianos, John; Ganapathy, Shrikanth; Raasch, Steven

A computing device having a cache memory (or “cache”) is described, as is a method for operating the cache. The method for operating the cache includes maintaining, in a history record, a representation of a number of bit errors detected in a portion of the cache. When the history record indicates that no bit errors or a single-bit bit error was detected in the portion of the cache memory, the method includes selecting, based on the history record, an error protection to be used for the portion of the cache memory.
