Software assisted power management
Embodiments include an apparatus comprising an execution unit coupled to a memory, a microcode controller, and a hardware controller. The microcode controller is to identify a global power and performance hint in an instruction stream that includes first and second instruction phases to be executed in parallel, identify a local hint based on synchronization dependence in the first instruction phase, and use the first local hint to balance power consumption between the execution unit and the memory during parallel executions of the first and second instruction phases. The hardware controller is to use the global hint to determine an appropriate voltage level of a compute voltage and a frequency of a compute clock signal for the execution unit during the parallel executions of the first and second instruction phases. The first local hint includes a processing rate for the first instruction phase or an indication of the processing rate.

System operated responsive to data bearing records
A depository operates to accept and make available deposit items to authorized users responsive at least in part to data read from data bearing records. The depository (10) includes a body (12) that bounds and interior area (14). The depository includes a door (18) that is controlled by a lock (24) so that only authorized users can access the interior area. The depository includes at least one input device (20) operative to receive data usable to identify users authorized to access the depository. At least one reading device (26) is operative to read indicia included on depository items so that depository items placed in or removed from the interior area can be tracked. The depository is in operative connection with a network (50) that enables the transport and tracking of deposit items.
Receiver detection system and receiver detection device
A receiver detection system includes a media access control (MAC) circuit, a common-mode voltage detector, and a receiver detector. The common-mode voltage detector is configured to detect whether a common-mode voltage satisfies a voltage condition, and to send a ready signal to the receiver detector after the common-mode voltage satisfies the voltage condition. The receiver detector is configured to start a detection process according to the ready signal and a detection start signal from the MAC circuit. In the detection process, the receiver detector sends out a detection signal for detecting whether a receiver exists, and then outputs a detection result to the MAC circuit, wherein the detection result indicates whether the receiver exists. The receiver detection system can prevent the receiver detector from starting the detection process before the common-mode voltage satisfies the voltage condition.

Controlling electrical power consumption for elements in an electronic device based on a platform electrical power limit
An electronic device includes an accelerated processing unit (APU) and multiple elements. The APU performs operations for a platform boost and throttle (PBT) controller. For the operations, the APU receives a platform electrical power limit, the platform electrical power limit being a limit on a total electrical power allowed to be consumed by a group of the elements at a given time. The APU then determines a present platform electrical power consumption. The APU next adjusts one or more operating parameters for specified elements from among the group of elements to control electrical power consumption by the specified elements based on a relationship between the present platform electrical power consumption and the platform electrical power limit.

Low-latency direct cloud access with file system hierarchies and semantics
Techniques described herein relate to systems and methods of data storage, and more particularly to providing layering of file system functionality on an object interface. In certain embodiments, file system functionality may be layered on cloud object interfaces to provide cloud-based storage while allowing for functionality expected from a legacy applications. For instance, POSIX interfaces and semantics may be layered on cloud-based storage, while providing access to data in a manner consistent with file-based access with data organization in name hierarchies. Various embodiments also may provide for memory mapping of data so that memory map changes are reflected in persistent storage while ensuring consistency between memory map changes and writes. For example, by transforming a ZFS file system disk-based storage into ZFS cloud-based storage, the ZFS file system gains the elastic nature of cloud storage.

System-on-chip having multiple circuits and memory controller in separate and independent power domains
Examples of the present disclosure generally relate to integrated circuits, such as a system-on-chip (SoC), that include a memory subsystem. In some examples, an integrated circuit includes a first master circuit in a first power domain on a chip; a second master circuit in a second power domain on the chip; and a first memory controller in a third power domain on the chip. The first master circuit and the second master circuit each are configured to access memory via the first memory controller. The first power domain and the second power domain each are separate and independent from the third power domain.
