Abstract: An installation structure of tree-shaped decoration includes a tree trunk and decorative branches. Two or more sets of hanging fittings are provided on the trunk along the axial direction. A plurality of decorative branches are connected to the hanging fittings and arranged according to the arrangement of the tree-shaped decoration. There are simulated decorations distributed on the decorative branches. The top of the decorative branches is provided with a hook to connect to a hanging setting. The decorative branches are also connected to at least one or more support rods along the extension direction. The other end of the support rods connects to another hanging fitting. The decorative branches can be batch-produced and hung to the trunk by the hanging fittings by adjusting the support rods according to the requirements of the tree shape. So, the installation is simple and quick. The tree decoration has good simulation effects while reducing the materials costs.

Abstract: A data processing unit may include a memory, processing elements (PEs), and a control unit. The memory may store weight blocks within a weight tensor of a neural network operation. Each weight block has an input channel (IC) dimension and an output channel (OC) dimension and includes subblocks. A subblock includes one or more weights having a first data precision and one or more other weights having a second data precision. The second data precision is lower than the first data precision. The control unit may distribute different ones of the subblocks to different ones of the PEs. A PE may receive a subblock and perform a first MAC operation on a weight having a first data precision and a second MAC operation on a weight having a second data precision. The first MAC operation may consume more computation cycles or more multipliers than the second MAC operation.

Abstract: A fractional-N phase-locked loop (PLL) that maintains phase coherence for an output signal with a plurality of possible output frequencies. The fractional-N PLL includes an oscillator, a phase detector to receive a reference clock signal and a feedback signal, and a multi-modulus divider coupled in a feedback path between the oscillator and the phase detector. A multi-modulus pattern generator supplies a drive pattern to the multi-modulus divider to achieve a desired change in frequency of the output signal. The multi-modulus pattern generator initiates the drive pattern at a boundary time to cause the output signal to have a substantially repeatable phase when restarting switching from any one of the output frequencies to any other of the output frequencies.

Abstract: In at least one embodiment, a method for measuring a distance between a first communications device including a first local oscillator and a second communications device including a second local oscillator includes unwrapping N phase values to generate N unwrapped phase values. N is an integer greater than one. Each of the N phase values indicate an instantaneous phase of a received signal. The method includes averaging the N unwrapped phase values to generate an average phase value. The method includes wrapping the average phase value to generate a final phase measurement of the first local oscillator with respect to the second local oscillator.
