    Abstract: Memory driver circuitry for driving a memory cell or cells of a memory device includes first driver path circuitry and selection circuitry. The first driver path circuitry includes driver circuitry that outputs a first signal and selection circuitry that receives the first signal and a second signal, and outputs a first selected signal. The first selected signal is a selected one of the first signal and the second signal. The selection circuitry of the memory driver circuitry receives a third signal and a fourth signal, and outputs a bias voltage signal to header circuitry of a memory cell. The bias voltage signal is a selected one of the third signal and the fourth signal. The third signal corresponds to the first selected signal.

    Abstract: Synchronizing system resources of a multi-socket data processing system can include providing, from a primary System-on-Chip (SOC), a trigger event to a global synchronization circuit. The primary SOC is one of a plurality of SOCS and the trigger event is provided over a first sideband channel. In response to the trigger event, the global synchronization circuit is capable of broadcasting a synchronization event to the plurality of SOCS over a second sideband channel. In response to the synchronization event, the system resource of each SOC of the plurality of SOCS is programmed with a common value. The programming synchronizes the system resources of the plurality of SOCS.

    Abstract: A level shifter may include a first transistor stack including at least four transistors arranged from a first voltage source to ground, including second and third transistors coupled with bias voltage source, and a fourth transistor coupled with an input to receive an input signal at a second voltage or ground. The level shifter may include a second transistor stack comprising at least four transistors arranged from the first voltage source to ground, including second and third transistors coupled with the bias voltage source, and a fourth transistor to receive an inverse of the input signal. A first transistor of the first transistor stack is cross-coupled with a first transistor of the second transistor stack. A level shifter may include a first output coupled with the second transistor stack between the second and third transistors to provide a first output signal at the first voltage or ground.

    Abstract: Methods and apparatus for calibrating a gain for a circuit block are disclosed. An example method includes receiving a plurality of quantizer offsets, where the plurality of quantizer offsets represent calibration data for a quantizer configured to quantize an output of the circuit block, determining one or more differences based on one or more first quantizer offsets of the plurality of quantizer offsets and on one or more second quantizer offsets of the plurality of quantizer offsets, and determining an incremental change in a gain associated with the circuit block based on the one or more differences.

    Abstract: An integrated circuitry (IC) device for a memory device includes driver circuitry, selection circuitry, clock generation circuitry, and self-time path circuitry. The driver circuitry generates a plurality of driver circuitry outputs. The selection circuitry selects one of the plurality of driver circuitry outputs based on a plurality of enable signals. The clock generation circuitry receives the selected one of the plurality of driver circuitry outputs from the selection circuitry, and generates a clock signal based on at least the selected one of the plurality of driver circuitry outputs from the selection circuitry. The self-time path circuitry of a memory receives the clock signal and generates a reset signal based on the clock signal. The plurality of driver circuitry outputs and the clock signal are based on the reset signal, and the self-time path circuitry corresponds to one or more columns of a memory bank.

    Abstract: A communication system includes link circuits that receive serial data over one or more input serial links. The link circuits include a primary link circuit and a secondary link circuit. The secondary link circuit includes a de-serializer circuit configured to receive the serial data from the one or more input serial links and convert the serial data into parallel data, and an aligner circuit comprising a memory. The aligner circuit stops at least one of storing the parallel data in the memory and reading the memory based on a channel bonding signal generated based on a channel bonding symbol within the serial data. The aligner circuit outputs the channel bonding signal to a finite state machine (FSM) circuit of the primary link circuit. The aligner circuit outputs the parallel data based on receiving a read signal from the FSM circuit of the primary link circuit.

    Abstract: Examples herein describe techniques for producing a three-dimensional (3D) die stack. The techniques include stacking a first die on top of a second die. The first die is offset from the second die in at least one of an x-direction and a y-direction, and a first routing sub-region of the first die aligns with a second routing sub-region of the second die. The techniques further include stacking a third die on top of the second die. The third die is offset from the second die in at least one of the x-direction and the y-direction, and a third routing sub-region of the third die aligns with a fourth routing sub-region of the second die.

    Abstract: Embodiments herein describe techniques to build multi-die field-programmable gate arrays (FPGAs) using chip-on-wafer (CoW) technology. In an embodiment, FPGA chiplets (i.e., dies) and an interposer substrate include respective hybrid bonding connectors. Metal layers of the interposer substrate are patterned to provide inter-die communications amongst the multiple dies via the hybrid bonding connectors, and the dies communicate with one another via the hybrid bonding connectors using a non-serialized protocol native to the FPGA. The dies may communicate with one another through edge-based hybrid bonding connectors (e.g., in a symmetrical fashion). The metal layers of the interposer substrate may also support intra-die communications (e.g., data, clocks, and/or controls) and/or provide power, clock(s), and/or configuration parameters to the dies via hybrid bonding connectors within central regions of the dies. The IC device may include more than 1000 tracks per millimeter (e.g., more than 1600, 2800, 3500, or greater).

    Abstract: Performance evaluation of a heterogeneous hardware platform includes implementing a traffic generator design in an integrated circuit. The traffic generator design includes traffic generator kernels including a traffic generator kernel implemented in a data processing array of the integrated circuit and a traffic generator kernel implemented in a programmable logic of the integrated circuit. The traffic generator design is executed in the integrated circuit. The traffic generator kernels implement data access patterns by, at least in part, generating dummy data. Performance data is generated from executing the traffic generator design in the integrated circuit. The performance data is output from the integrated circuit.
