    摘要: Systems and methods to implement a multi-level memory system having a volatile memory and a non-volatile memory are implemented. A home agent may control memory access to both a volatile main memory and a non-volatile second level memory. The second level memory may be inclusive of the main memory. In an embodiment, the home agent may be configured to manage the memory system in a low power state. In a low power state, the volatile memory may be shut down and the non-volatile memory utilized as the only local memory. In an embodiment, the home agent may be configured to manage error recovery for the main memory by recovering the data saved locally in the second level memory. In an embodiment, multiple cores may access the second level memory.

    摘要: Methods, systems, and apparatus for implementing raw memory transactions. An SoC is configured with a plurality of nodes coupled together forming a ring interconnect. Processing cores and memory cache components are operatively coupled to and co-located at respective nodes. The memory cache components include a plurality of last level caches (LLC's) operating as a distributed LLC and a plurality of home agents and caching agents employed for supporting coherent memory transactions. Route-back tables are used to encode memory transactions requests with embedded routing data that is implemented by agents that facilitate data transfers between link interface nodes and memory controllers. Accordingly, memory request data corresponding to raw memory transactions may be routed back to requesting entities using headerless packets.

    摘要: A method and apparatus for a microprocessor with a cache that has the advantages given by a victim cache without physically having a victim cache is disclosed. In one embodiment, a victim flag may be associated with each way in a set. At eviction time, the way whose victim flag is true may be evicted. However, the victim flag may be reset to false if a superceding request arrives for the cache line in that way. Another cache line in another way may then have its victim flag made true.
