    摘要: One or more implementations of the subject technology may enable a bond-on-pad (BoP) substrate technology that can eliminate the need to utilize a solder-on-pad (SoP) process. Unlike an SoP process, a BoP Process does not require a solder bump to be formed on a bump pad to attach a joint to a bump pad. The size of an opening on a bump pad for a BoP process may be larger than that of an SoP process. A BoP process may use a solder mask having multiple thicknesses and may be thinner near the bump pads. A BoP process may use a joint having a copper pillar and a solder cap. A BoP process can be used with an underfill or a molding compound technology.

    摘要: The disclosed systems and methods provide methods and systems for providing power throttling adapted for high performance network switches. A method includes determining, for each of a plurality of measurement periods within a thermal average period, an energy usage estimate for a packet processing block configured to process ingress packets at a power gated clock rate. The method includes determining, for each of the plurality of measurement periods, a target clock rate for the packet processing block based on the determined energy usage estimates to meet a target energy value that is averaged for the thermal average period. The method includes adjusting, for each of the plurality of measurement periods, the power gated clock rate towards the target clock rate, wherein the adjusting causes the packet processing block to process the ingress packets at the adjusted power gated clock rate.

    摘要: A method for channel smoothing with transmit beamforming includes transmitting, by a first device, a non-data-packet (NDP) frame to a second device. The method also includes receiving, by the second device, the NDP frame and transmitting a compressed report to the first device. The method further includes receiving, by the first device, the compressed report and deriving a first beamforming matrix from the compressed report. A second beamforming matrix is generated employing a processing known to the second device, and a data frame is transmitted to the second device using the second beamforming matrix.

    摘要: A filter device configured to directly connect to a differential power amplifier of a transmit chain circuit. The filter device may include a transformer and a filter configured as a half lattice equivalent topology and having a single-ended output. The filter may be a lattice filter configured as a full lattice topology or a lattice equivalent filter configured as a half lattice equivalent topology. The filter includes a first branch having a first impedance network of one or more first impedance elements and a second branch having a second impedance network of one or more second impedance elements. The single-ended output of the filter device may connect to an antenna switch that is in turn connected to an antenna.

    摘要: In the subject architecture flexible binary arithmetic coding system, coding circuitry of an electronic device may receive video data that is to be coded (e.g., to be encoded or decoded) by binary arithmetic coding. The coding circuitry may also compute at least one of a least probable symbol (LPS) range or a most probable symbol (VIPS) range based on a multiplication operation (e.g., without performing a table look-up operation). The coding circuitry may perform binary arithmetic coding on the video data using the at least one of the LPS range or the MPS range. The computation of the LPS range and/or the MPS range using the multiplication operation may have a lower computational cost than using a table look-up operation.
