A motor driver may include a controller, a space vector modulator, a converter and a detector. The space vector modulator may generate driving signals under control of the controller according to a space vector pulse width modulation ('SVPWM') scheme. The converter may derive AC signals from the driving signals received from the space vector modulator and may output the AC signals to the USM motor. The detector may generate feedback signals representing current and voltage supplied to the USM motor. The controller may revise estimates of space vectors, based on measurements from the detector, to control the space vector modulator to adjust frequencies, amplitudes, or phase angles of the plurality of AC signals.

Space vector pulse modulation based motor driver

The present disclosure provides a stream processor, an associated stream controller and compiler, and associated methods for data processing, such as image processing. In some embodiments, a method includes defining a kernel pattern associated with an image frame, and processing the image frame using the defined kernel pattern. The method can further include generating a kernel switch lookup table based on the defined kernel pattern. In various implementations, the stream controller is operable to direct execution of kernels on the image frame according to the defined kernel pattern and the kernel switch lookup table.

A circuit may include a splitter, a controller, and a termination. The splitter may generate, based upon input signals, a plurality of output signals, wherein at least one of the input signals is in more than one different modes at different times and the output signals comprise a first set of the output signals generated based upon comparison of pairs of signals of the first set against each other and a second set of the output signals generated based upon comparison of each signal of the second set to a predetermined threshold voltage. The controller may determine, based upon the second set of the output signals, whether the input signals are in the one of the more than one different modes to generate one or more control signals. The termination may connect loads to each of the input lines, based upon the one or more control signals.
