摘要： Systems and methods for direct memory access are described. One example system includes a memory module that includes a first memory portion that maintains transfer descriptors of direct memory access (DMA) channels, and a second memory portion that maintains transfer descriptors of enabled DMA channels. The system includes a controller coupled to the memory module, the controller includes one or more DMA channels coupled to a system bus, a channel arbiter that selects one of the enabled DMA channels as an active DMA channel for data transfer including re-arbitrating after each burst or beat in a given transfer, and an active channel buffer that receives a transfer descriptor of the active DMA channel from the second memory portion. The controller is configured to write back the transfer descriptor of the active DMA channel into the second memory portion when the active DMA channel loses arbitration.

摘要： A microcontroller system includes a main voltage regulator and a low power voltage regulator having a static current consumption less than the static current consumption of the main voltage regulator. A power state controller enables the low power voltage regulator during a power saving mode. On exiting the power saving mode, the power state controller enables the main voltage regulator and disables the low power voltage regulator after determining that the main voltage regulator is ready. The switching circuitry can be asynchronous.

摘要： A microcontroller system includes a power manager that is configured to, during a power saving mode, configure an interrupt delaying module to receive and hold an interrupt from an interrupt source. In response to receiving the interrupt from the interrupt source, the power manager causes the microcontroller system to exit the power saving mode. Upon exiting the power saving mode, the power manager configures the interrupt delaying module to release the interrupt.

摘要： A controller circuit for the control of a power converter is disclosed. An example controller circuit generates a waveform that drives a switch that controls the power converter. The controller circuit includes a divider module that generates a modification factor based on a ratio of the two input signals of the module. The circuit includes a module that generates a first waveform configured for a critical conducting mode of operation of a power converter and an on-time adjuster module that modifies the first waveform based on the modification factor and generates a second waveform. The second waveform is delivered to the switch. An example modification factor is the ratio of the output voltage to the rectified input voltage of the power converter.
