Abstract: Accumulators for reducing frequency of samples and related apparatuses, systems, and methods are disclosed. An apparatus includes a first accumulator and a second accumulator. The first accumulator provides a first total. The first total corresponds to a sum of a current sample value of an input signal and a previous value of the first total. The second accumulator provides a second total. The second total corresponds to a sum of the first total and a previous value of the second total.

Abstract: Compact timestamps and related methods, systems and devices are described. An encoder is configured to generate compact timestamps of the disclosure by sampling states of linear feedback shift registers (LFSRs). A decoder may be configured to determine timing information responsive to the compact timestamps.

Abstract: One or more examples relate, generally, to an orientation of a rotor. Some examples relate to an apparatus. The apparatus may include sample-accumulation logic to generate, over a time duration, a value indicative of inductance at least partially responsive to a probe signal provided to a stator of a motor. The apparatus may also include a probe-current discriminator to generate a further value indicative of an orientation of a rotor of the motor at least partially responsive to the generated value. The apparatus may also include update logic to update a process variable of a control loop at least partially responsive to a state of the further value.

Abstract: One or more examples relate, generally, to reducing error in estimated angular position of a rotor of a motor. In one example, a method comprises generating an error signal indicating error in the estimated angular position; determining an adjustment amount associated with an estimated torque-producing component of motor winding current of a stator of the motor; generating an adjustment signal corresponding to the determined adjustment amount; and combining the error signal and the adjustment signal to generate a corrected error signal.
