    摘要: Method and apparatus to scrub memory is disclosed. A patrol request, for example a read/write request, may be raised to the memory command scheduler in an out of order memory controller to scrub the memory. The patrol read/write request may be raised as and when patrol interval timer expires. The patrol read/write request may also be raised based on presence of a transaction in-flight to the memory, retry response from the memory command scheduler and correctable or non-correctable error response from the memory command scheduler. An interrupt may be raised to a processor upon completion response from the memory command scheduler.

    摘要: Embodiments of the invention describe systems and processes directed towards reducing memory subsystem idle power consumption. Embodiments of the invention enable low power states for various components of a memory subsystem under certain operating conditions, and exiting said low power states under certain operating conditions.Embodiments of the invention may comprise of logic, modules or any combination thereof, to detect operating conditions in a computing system. Some of these operating conditions may include, but are not limited to, a memory controller being empty of transactions directed towards its respective memory unit(s), a processor core executing a processor low-power mode, and a processor socket (operatively coupling the processing core and the memory unit) executing an idle mode. In response to detecting said operating conditions, embodiments of the invention may execute a low-power idle state for the memory unit(s) and various components of the memory subsystem.

    摘要: A method is described that involves determining that software state information of program code is to be made visible to a monitoring system. The method also involves initiating the writing of the software state information into a register. The method also involves waiting for the software state information to be placed onto a link within a link based computing system.

    摘要: Method and apparatus to reduce latency of command while maintaining the thermal level of a memory in a safe value is disclosed. A memory request with or without a command to a memory may be scheduled by a memory request scheduler. If the memory request has the command to the memory then a memory command credit counter for that memory may be decreased. If the memory request does not have the command to the memory then the memory command credit counter for that memory may be increased. The increased credits of the memory command credit counter may be used to execute the memory requests frequently and the latency of the command may thus be reduced.
