Data re-encoding for energy-efficient data transfer in a computing device

The energy consumed by data transfer in a computing device may be reduced by transferring data that has been encoded in a manner that reduces the number of one “1” data values, the number of signal level transitions, or both. A data destination component of the computing device may receive data encoded in such a manner from a data source component of the computing device over a data communication interconnect, such as an off-chip interconnect. The data may be encoded using minimum Hamming weight encoding, which reduces the number of one “1” data values. The received data may be decoded using minimum Hamming weight decoding. For other computing devices, the data may be encoded using maximum Hamming weight encoding, which increases the number of one “1” data values while reducing the number of zero “0” values, if reducing the number of zero values reduces energy consumption.

Hardware system identification circuitry

An information handling system includes an identification resistor, calibration circuitry, and a system-on-a-chip (SOC). The SOC sets the calibration line to a first digital state to place the calibration circuitry in an inventory mode. While the calibration circuitry is in the inventory mode, the SOC determines an inventory amount of time to charge the capacitor to a voltage substantially equal to a threshold voltage. The SOC then sets the calibration line to a second digital state to place the calibration circuitry in a calibration mode. While the calibration circuitry is in the calibration mode, the SOC determines a calibration amount of time to charge the capacitor to the voltage substantially equal to the threshold voltage. The SOC determines a resistance of the identification resistor based on the inventory amount of time and the calibration amount of time. The SOC also determines bit strapping information corresponding to the determined resistance.

Implementations of the present disclosure are directed to systems and methods for reducing design complexity and critical path timing challenges of credit return logic. A wide bus supports simultaneous transmission of multiple flits, one per lane of the wide bus. A source device transmitting flits on a wide bus selects from among multiple credit return options to ensure that only one of the multiple flits being simultaneously transmitted includes a credit return value. In some example embodiments, the receiving device checks only the flit of one lane of the wide bus (e.g., lane 0) for credit return data. In other example embodiments, the receiving device uses a bitwise-OR to combine the credit return data of all received flits in a single cycle.

An electronic eyewear device includes first and second systems-on-chip (SoCs) having independent time bases. The first and second SoCs are connected by a shared general purpose input/output (GPIO) connection and an inter-SoC interface. The first and second SoCs are synchronized to each other by the first SoC asserting the shared GPIO connection to the second SoC where assertion of the message to the shared GPIO connection triggers an interrupt request (IRQ) at the second SoC. The first SoC records a first timestamp for assertion of the message to the GPIO connection, and the second SoC records a second timestamp of receipt of the IRQ. The first SoC sends a message including the first timestamp to the second SoC over the inter-SoC interface. The second SoC calculates a clock offset between the first and second SoCs as a difference between the first and second timestamps.

An electronic eyewear device includes first and second systems on a chip (SoCs) having independent time bases and an inter-SoC interface that connects the first and second SoCs. The operations of the first and second SoCs are synchronized by aligning the time bases for the SoCs using a modified PTP technique. The technique includes the second SoC receiving a time synchronization message from the first SoC over the inter-SoC interface, recording a local timestamp of receipt of the time synchronization message, receiving a master timestamp corresponding to a timestamp recorded by the first SoC corresponding to the time of sending the time synchronization message by the first SoC, and calculating a time offset between the local timestamp and the master timestamp. The time bases of the first SoC and second SoC are then aligned using the calculated time offset. To account for transmission delays, multiple time offsets may be averaged.
