Abstract: A method for performing stutter of dynamic random access memory (DRAM) where a system on a chip (SOC) initiates bursts of requests to the DRAM to fill buffers to allow the DRAM to self-refresh is disclosed. The method includes issuing, by a system management unit (SMU), a ForceZQCal command to the memory controller to initiate the stutter procedure in response to receiving a timeout request, such as an SMU ZQCal timeout request, periodically issuing a power platform threshold (PPT) request, by the SMU, to the memory controller, and sending a ForceZQCal command prior to a PPT request to ensure re-training occurs after ZQ Calibration. The ForceZQCal command issued prior to PPT request may reduce the latency of the stutter. The method may further include issuing a ForceZQCal command prior to each periodic re-training.

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.

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.

Abstract: A disclosed technique includes transmitting data in a first buffer associated with a first display pipe to a first display associated with the first display pipe; transmitting data in a second buffer associated with a second display pipe to the first display; requesting wake-up of a memory; and refilling one or both of the first buffer and the second buffer from the memory.

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.

Abstract: Various energy efficient data encoding schemes and computing devices are disclosed. In one aspect, a method of transmitting data from a transmitter to a receiver connected by plural wires is provided. The method includes sending from the transmitter on at least one but not all of the wires a first wave form that has first and second signal transitions. The receiver receives the first waveform and measures a first duration between the first and second signal transitions using a locally generated clock signal not received from the transmitter. The first duration is indicative of a first particular data value.

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.
