摘要： Adaptive thresholding technique for power supplies during margining events. A power supply may include a fault detection mechanism for monitoring an output voltage of the power supply to determine whether the output voltage is greater than a first over-voltage threshold or less than a first under-voltage threshold. If a margining event changes the power supply output voltage, the fault detection mechanism may dynamically change a first over-voltage threshold and a first under-voltage threshold based on the margining event to a second over-voltage threshold and a second under-voltage threshold. Then, during the margining event, the fault detection mechanism may monitor the output voltage of the power supply to determine whether the output voltage is greater than a second over-voltage threshold or less than a second under-voltage threshold. The fault detection mechanism may dynamically change a fault threshold in proportion to the change in the power supply output voltage.

摘要： A method is disclosed for converting DC power from a first voltage level on an input to a different voltage level on an output for delivery to a load. The method includes switching current in a switching operation from the input to the output through an inductive element and measuring the voltage/current parameters on the input and output. A control algorithm is then utilized to determine control parameters necessary to make a control move to effect the switching operation, the control algorithm utilizing as inputs the measured voltage/current parameters. A digital control system controls the switching operation, which digital control system is operable to be controlled by the control algorithm. Configuration data is received on a serial data bus for configuring the control algorithm. Thereafter, the operation of the control algorithm is modified in response to receiving the configuration information.

摘要： A precision oscillator for an asynchronous transmission system. An integrated system on a chip with serial asynchronous communication capabilities includes processing circuitry for performing predefined digital processing functions on the chip and having an associated on chip free running clock circuit for generating a temperature compensated clock. An asynchronous on-chip communication device is provided for digitally communicating with an off-chip asynchronous communication device, which off-chip asynchronous communication device has an independent time reference, which communication between the on-chip communication device and the off-chip asynchronous communication device is effected without clock recovery. The asynchronous on-chip communication device has a time-base derived from the temperature compensated clock. The temperature compensated clock provides a time reference for both the processing circuitry and the asynchronous on-chip communication device.

摘要： The control precision of one or more parameters of an integrated circuit (IC), for example the output voltage of a voltage regulator comprised in the IC, may be improved even when using inaccurate components external to the IC. Control of the output voltage, or any parameter, using components external to the IC may include coupling a resistor to the IC and measuring the actual resistance value of the resistor, and based on the measured value, selecting a nominal resistance value from a set of resistance values previously specified by the user. The output voltage, or parameter, may be generated according to the nominal resistance value instead of the actual resistance value, thereby reducing the error that may be incurred due the actual resistance value of the resistor not matching the expected nominal value of the resistor. The difference between each adjacent resistance value in the set of resistance values may be selected to be greater than the greatest measurement error that may be incurred during measuring the actual resistance value.

摘要： Techniques are disclosed relating to a system that implements direct memory access (DMA). In one embodiment, an apparatus is disclosed that includes a dedicated data transfer management (DTM) circuit. The DTM circuit is configured to provide commands to a direct memory access (DMA) controller coupled to a bus to facilitate the DMA controller retrieving portions of a data object to be transmitted to a peripheral circuit via the bus. In some embodiments, the DTM is configured to assemble a data packet having a payload supplied by a processor, where the DTM circuit is configured to assemble the data packet by generating direct memory access (DMA) requests for the DMA controller. In such an embodiment, the DMA requests cause a plurality of peripheral circuits coupled to the bus to transfer portions of the data packet over the bus.
