  • Patent number: 11663001
    Abstract: Systems, apparatuses, and methods for implementing a family of lossy sparse load single instruction, multiple data (SIMD) instructions are disclosed. A lossy sparse load unit (LSLU) loads a plurality of values from one or more input vector operands and determines how many non-zero values are included in one or more input vector operands of a given instruction. If the one or more input vector operands have less than a threshold number of non-zero values, then the LSLU causes an instruction for processing the one or more input vector operands to be skipped. In this case, the processing of the instruction of the one or more input vector operands is deemed to be redundant. If the one or more input vector operands have greater than or equal to the threshold number of non-zero values, then the LSLU causes an instruction for processing the input vector operand(s) to be executed.

  • Patent number: 11663073
    Abstract: An apparatus and method for efficiently transmitting data are described. A transmitter sends data to a receiver. An encoder of the transmitter divides a received first block of data into multiple sub-blocks. The encoder selects a portion of each sub-block to compare to one another. A portion in a particular sub-block has a same offset and a same size as other portions of other sub-blocks. If the encoder determines the multiple portions match one another, the encoder sends, to the receiver, a second block of data corresponding to the first block of data. The second block of data has a same size as a size of the received first block of data, and the second block of data includes security data from one of multiple error correction schemes. Therefore, the second block of data provides security without increasing an amount of data to transmit.

  • Patent number: 11656796
    Abstract: A data processor includes a fabric-attached memory (FAM) interface for coupling to a data fabric and fulfilling memory access instructions. A requestor-side adaptive consistency controller coupled to the FAM interface requests notifications from a fabric manager for the fabric-attached memory regarding changes in requestors authorized to access a FAM region which the data processor is authorized to access. If a notification indicates that more than one requestor is authorized to access the FAM region, fences are activated for selected memory access instructions in a local application.

  • Patent number: 11656732
    Abstract: Systems, apparatuses, and methods for implementing enhanced scaling techniques for display objects are disclosed. When graphical content is created by an application, display objects register with a scaling manager to be notified of display scaling events. These display scaling events can be caused by changing displays, changing resolution or other parameters on a display, changing a text size, resizing one or more graphical elements, or otherwise. When a display scaling event is detected, display objects are notified of the event by the scaling manager. If a given display object makes a decision to change the amount of space it occupies based on the event, the given display object notifies its parent object of the desired change. The parent can then decide whether to allow the change and/or to make adjustments to other display objects to accommodate the change sought by the given display object.

  • Patent number: 11657856
    Abstract: Systems, apparatuses, and methods for implementing a sampling circuit with increased headroom are disclosed. A sampling circuit includes at least a pair of input signal transistors connected via their drains to a cross-coupled pair of state nodes. The cross-coupled pair of state nodes are coupled to a tail transistor device via the sources of N-type transistors. When clock goes low, the circuit precharges the cross-coupled pair of state nodes while simultaneously attempting to amplify the difference between the pair of input signals. The amplification is performed by a pair of transistors in series between a source of each input signal transistor and ground. Each gate of the pair of transistors is connected to an inverted clock signal. When clock goes high, the circuit stops precharging and a voltage difference between the pair of input signals is regenerated to create a resulting differential voltage on the pair of state nodes.

  • Patent number: 11650650
    Abstract: A processing unit includes a plurality of components configured to execute instructions and a controller. The controller is configured to determine a power consumption of the processing unit, determine a waiting status of the processing unit based on waiting statuses of components, and selectively modify an operating state of the processing unit based on the waiting status and the power consumption of the processing unit. In some cases, the operating state is modified in response to a percentage of the components that are waiting for an action to complete being below a threshold percentage and the power consumption of the processing unit being below a power limit. In some cases, the controller identifies a pattern in the power consumption by the processing unit and modifies the operating state of the processing unit to increase the power consumption of the processing unit based on the pattern identified by the controller.
