摘要： A processing unit of a packet processing node initiates a transaction with an accelerator engine to trigger the accelerator engine for performing a processing operation with respect to a packet, and triggers the accelerator engine to perform the processing operation. The processing unit attempts to retrieve a result of the first processing operation from a memory location to which a result is to be written. It is determined whether the result has been written to the memory location, and when it is determined that the result has not yet been written to the memory location, the processing unit is locked until at least a portion of the result is written to the memory location.

摘要： The present disclosure describes apparatuses and techniques for device-based die authentication. In some aspects, an intensity of a particle beam is varied during semiconductor processing to provide a semiconductor die having devices of varied values. In other aspects, different areas of semiconductor dies are exposed during semiconductor processing to provide semiconductor dies with devices that vary in value from one die to the next. For each semiconductor die, a value generated based on the values of the die's respective devices can be associated with that die thereby enabling subsequent authentication of the semiconductor die.

摘要： A method for generating OFDM signals is implemented in a device operating according to a communication protocol. The protocol defines non-duplicate mode data units corresponding to single component channels of a BSS channel, and non-duplicate mode data units corresponding to sets of adjacent component channels. Non-duplicate mode data units corresponding to a set of component channels have more lower-edge and/or upper-edge guard tones than non-duplicate mode data units corresponding to single component channels. The method includes determining that a duplicate mode will be utilized for an OFDM transmission in the set of component channels and, in response, generating a duplicate mode data unit. The duplicate mode data unit has fewer lower-edge and/or upper-edge guard tones than a non-duplicate mode data unit corresponding to a set of component channels, and includes one duplicate of the non-duplicate mode data unit corresponding to the single component channel for each adjacent component channel.

摘要： A system including memory to store a plurality of sets of values, where each set is used to control speed of a different type of motor. A pulse width modulation (PWM) module receives an input indicating a type of motor sensed in the system, selects a set corresponding to the type of the sensed motor, and generates, based on the selected set, a pulse width modulation signal to control speed of the sensed motor. A speed module receives a requested speed for the sensed motor and generates an output indicating a range of speed corresponding to the requested speed. The PWM module selects, based on the range of speed, a value from the selected set; shifts, based on the selected value, the pulse width modulation signal; and adjusts, based on the shifted pulse width modulation signal, the speed of the sensed motor by adjusting torque applied to the sensed motor.

摘要： A field of a preamble of the data unit is decoded using a tail biting technique, including decoding a received cyclic redundancy check (CRC) included in the field. A first CRC for the field is generated using a first CRC generation scheme, and a second CRC for the field is generated using a second CRC generation scheme. The first generated CRC and the second generated CRC are compared to the received CRC. It is determined that the data unit conforms to a first communication protocol when the first generated CRC matches the received CRC, and it is determined that the data unit conforms to a second communication protocol when the second generated CRC matches the received CRC.
