摘要： An electronic circuit is for switching a power transistor having a drain coupled to a drain node, a source coupled to a lower voltage supply, and a gate coupled to a gate node. The electronic circuit includes first current generation circuitry to generate a first current to flow into the gate node in response to assertion off an ON signal, the first current being substantially constant. Second current generation circuitry generates a second current to flow into the gate node in response to deassertion of an OFF signal, the second current being inversely proportional to a gate to source voltage of the power transistor. First comparison circuitry compares a drain voltage at the drain node to a reference voltage, and activates third current generation circuitry to generate a third current to flow into the gate node when the drain voltage is less than the reference voltage.

摘要： A method of starting a permanent magnet synchronous motor (PMSM) with field oriented control (FOC) includes: opening a first control loop of the PMSM; setting a first direction for a first current component of the PMSM; aligning a rotor of the PMSM to the first direction; after aligning the rotor, setting a second direction for the first current component, where the second direction is rotated from the first direction by 90 degrees; after setting the second direction, starting the rotor while the first control loop of the PMSM remains open; after starting the rotor, increasing a rotation speed of the rotor by operating the first control loop in a first closed-loop mode; and after increasing the rotation speed of the rotor, controlling the rotation speed of the rotor by operating the first control loop in a second closed-loop mode different from the first closed-loop mode.

摘要： A method for reporting touch on a touchscreen includes detecting first touch data from the touchscreen corresponding to a first touch on the touchscreen; determining coordinates of the first touch from the first touch data; reporting the coordinates of the first touch at a first time; determining predicted coordinates of a second touch based on a linear regression of historical touch data; and reporting the predicted coordinates of the second touch at a second time, where the second time occurs after the first time.

摘要： A device includes a circular buffer, which, in operation, is organized into a plurality of subsets of buffers, and control circuitry coupled to the circular buffer. The control circuitry, in operation, receives a memory load command to load a set of data into the circular buffer. The memory load command has an offset parameter indicating a data offset and a subset parameter indicating a subset of the plurality of subsets into which the circular buffer is organized. The control circuitry responds to the command by identifying a set of buffer addresses of the circular buffer based on a value of the offset parameter and a value of the subset parameter, and loading the set of data into the circular buffer using the identified set of buffer addresses.

摘要： An electronic device includes a touch screen for a touch sensitive display carried by a portable housing. The electronic device is configured to operate in a high detection threshold mode to determine whether an object is in contact with the touch sensitive display, and operate in a low detection threshold mode to determine whether the object is adjacent to the touch sensitive display, based on lack of detection of the object being in contact with the touch sensitive display. The electronic device is further configured to determine whether the object s in contact with a peripheral edge of the portable housing by determining whether the object is adjacent opposite sides of the touch sensitive display, based on detection of the object being adjacent to the touch sensitive display.

摘要： A cache memory is organized into a plurality of ways and a plurality of address lines. In response to a miss, the cache memory selects a way of the plurality of ways based on a first control variable indicating a way of the plurality of ways and a set of second control variables associated with the address line and with respective ways. Data associated with the miss is written to the selected way. Second control variables associated with other ways are reset if all of the second control variables indicate the associated way was recently replaced. The second control variable associated with the selected way is set to indicate the selected way was recently replaced. The first control variable is set to indicate the selected way. Current values of the first control variable and of the set of second control variables are maintained in the event of a hit.
