  • Patent number: 11476947
    Abstract: A low-power coherent receiver is enabled with enhanced performance for intra-datacenter reach optical interconnection applications using several techniques. The first is a coherent skew adjustment technique which enables lower-power baud-rate ADC sampling and baud-rate-spaced coherent equalization. The second is a real-valued or mixed-valued low-power coherent equalization technique, where a single-tap real-valued 4×4 MIMO equalizer plus four real-valued or two mixed-valued single-input single-out (SISO) equalizers are used for simultaneous polarization recovery, in-phase and quadrature (I/Q) phase error correction, and bandwidth equalization. The third is a power-efficient dual-DSP architecture to enhance coherent receiver performance, in which a complementary low-speed coherent DSP is introduced for optimal I/Q phase error correction and constellation decision parameters determination through more sophisticated algorithms that are too power hungry to be implemented in the primary high-speed DSP.

  • Patent number: 11262402
    Abstract: An address and command port interface selectively enables JTAG TAP domain operations and Trace domain operations within an IC. The port carries TMS and TDI input and TDO output on a single pin and receives a clock signal on a separate pin. The addressable two pin interface loads and updates instructions and data to the TAP domain within the IC. The instruction or data update operations in multiple ICs occur simultaneously. A process transmits data from an addressed target device to a controller using data frames, each data frame comprising a header bit and data bits. The logic level of the header bit is used to start, continue, and stop the data transmission to the controller. A data and clock signal interface between a controller and multiple target devices provides for each target device to be individually addressed and commanded to perform a JTAG or Trace operation.

  • Patent number: 11249511
    Abstract: The disclosure relates to clock-crossing elements that may be used to transfer data between different clock domains. The embodiments include dual clock first-in first-out (FIFO) buffers that may employ toggle-based protocols to manage the transference of information regarding the state of the FIFO buffer. The toggle-based protocols may include a feedback-based handshake and bit-sliced toggle lines to prevent errors due to differences between the clock signals in the different clock domains.

  • Patent number: 11205152
    Abstract: Systems and methods to warehouse, handle, and deliver products are disclosed. The system can comprise a vendor-based virtual network that is associated with a supplier-based physical network. The system can enable vendors with institutional, market, or industry knowledge to manage inventory, logistics, and delivery more efficiently. The system can enable vendors to configure a virtual warehouse and delivery network based on the institutional, market, or industry knowledge. The virtual network can be mapped—behind the scenes—to physical warehouses and delivery networks by warehousing providers (“providers”) based at least in part on the virtual network. The provider can then adjust the physical network based on market knowledge, research, physical sales, warehouse and personnel availability, weather, and other factors. The provider can also offer periodic data to the vendor based on physical sales and delivery information to enable both the virtual and physical networks to converge on an efficient solution.

  • Patent number: 11137794
    Abstract: Methods and systems for synchronization of multiple processing cores of an electronic control system are disclosed. The electronic control system is configured to monitor and control operation of a multicore architecture employing one or more processing cores to generate a time reference signal and/or to synchronize with the time reference signal. In some examples, the system employs a single master processor to generate the reference synchronization signal (e.g., a master sync signal). In examples, a rising edge of the partition time reference signal is used as the marker of reference time zero (e.g., the start of a new partition frame). If a core is out of sync with the master sync signal, that core adjusts one or more timing characteristics to align the associated signal with the reference signal.

  • Patent number: 11119790
    Abstract: Systems, methods, and apparatus for improving bus latency for trigger activation are described. One method includes using configuration information received from a serial bus and stored in a holding register to reconfigure a peripheral device in accordance with timing indicated by at least one edge in clock pulses transmitted on a clock line of the serial bus. A trigger is activated by detection of a first edge in the clock pulses. Bits of the holding register are transferred to a register that controls elements of the peripheral device when the trigger is actuated. The trigger may be activated as indicated by trigger activation information received in a datagram. The trigger may be activated as indicated by a start condition transmitted on the serial bus. The trigger may be enabled or disabled based on signaling state of a data line of the serial bus when the first edge is detected.
