Abstract: A processor includes one or more cores having cache, a cache home agent (CHA), a near memory controller, to near memory, and a far memory controller, which is to: receive a first memory read operation from the CHA directed at a memory address; detect a miss for the first memory address at the near memory; issue a second memory read operation to the far memory controller to retrieve a cache line, having first data, from the memory address of far memory; receive the cache line from the far memory controller in response to the second memory read operation; and send the cache line to the CHA with a forced change to a directory state of the cache line at the CHA, the forced change to cause the CHA to snoop remote sockets to maintain data coherence for the cache line in an absence of directory state in the far memory.

Abstract: A method of enhancing one or more fields of a master database record based on a consumption of one or more data points provided via a third-party data subscription service is disclosed. An aggregated view corresponding to a master database record is accessed. The aggregated view identifies correspondences between the one or more fields of the master database record and the one or more data points provided via the third-party data subscription service. Based on a determination that one or more consumption criteria are met, the one or more data points are consumed and stored in a central database. The one or more fields of the master database record are updated based on the one or more consumed data points. The enhanced master database record is provided via a network to one or more computerized processes associated with one or more consumers of the enhanced master database record.

The method has been found to anticipate ammonia and NOx slip.

Abstract: A power management controller (PMC) for resetting various voltage domains of an integrated circuit (IC) generates and transmits first and second voltage domain input signals to first and second voltage domains, respectively, and generates corresponding reset signals for resetting the first and second voltage domains. The PMC generates a first master reset signal indicative of resetting the first and second voltage domains when the first and second voltage domains are booting. The PMC generates a second master reset signal indicative of resetting the first and second voltage domains when the IC is in a functional mode. The PMC determines whether the first and second voltage domains are non-functional and if at least one is non-functional, then the PMC masks a respective one of the first and second reset signals.
