摘要:
Methods and apparatus for reducing the amount of latency involved when accessing, by a remote device, data residing in a cache of a processor are provided. For some embodiments, virtual channels may be utilized to conduct request/response transactions between the remote device and processor that satisfy a set of associated coherency rules.

摘要:
Methods and apparatus that may be utilized to maintain coherency of data accessed by both a processor and a remote device are provided. Various mechanisms, such as a remote cache directory, castout buffer, and/or outstanding transaction buffer may be utilized by the remote device to track the state of processor cache lines that may hold data targeted by requests initiated by the remote device. Based on the content of these mechanisms, requests targeting data that is not in the processor cache may be routed directly to memory, thus reducing overall latency.

摘要:
Computer systems with direct updating of cache (e.g., primary L1 cache) memories of a processor, such as a central processing unit (CPU) or graphics processing unit (GPU). Special addresses are reserved for high speed memory. Memory access requests involving these reserved addresses are routed directly to the high speed memory. Memory access requests not involving these reserved addresses are routed to memory external to the processor.
