  • Patent number: 12014084
    Abstract: A non-volatile memory receives a data read request from a processing core of a plurality of processing cores. The read request is directed to a data partition of a non-volatile memory. The non-volatile memory determines whether to process the read request using read-while-write collision management. When it is determined to process the read request using read-while-write collision management, an address associated with the read request is stored in an address register of a set of registers associated with the processing core. Write operations directed to the data partition are suspended. A read operation associated with the read request is executed while the write operations are suspended and data responsive to the read operation is stored in one or more data registers of the set of registers. The data stored in the one or more data registers of the set of registers is provided to the processing core.

The first integer number is indicative of the integer number of clock periods of the switch-on duration and the second integer number is indicative of the integer number of the additional fractions 1/n of the clock period of the switch-on duration. The third integer number is indicative of the integer number of clock periods of the switch-off duration, and the fourth integer number is indicative of the integer number of the additional fractions 1/n of the clock period of the switch-off duration.

  • Publication number: 20240192863
    Abstract: System, method, and circuitry for generating content for a programmable computing device based on user-selected memory regions. Contiguous regions that share memory access attributes are merged, interleaved contiguous regions that share at least one nested attribute are defined into combined regions, and remaining regions are defined as separate independent regions. A memory protection unit (MPU) region size closest to a size of each defined region is identified. If the start address of each region aligns with the address structure of the MPU region size, then those regions are assigned to MPU regions having the MPU region size; otherwise, another MPU size that aligns with the size of the regions is selected and those regions are assigned to MPU regions having that size. Content is generated to configure settings of MPU regions of the programmable computing device for the merged contiguous regions, the combined region, and the independent regions.

  • Publication number: 20240195405
    Abstract: A receiver circuit receives a differential signal that includes positive and negative spikes, and produces an output signal as a function of the differential signal. A first comparator produces an intermediate set signal that includes a pulse at each positive spike of the differential signal, and a second comparator produces an intermediate reset signal that includes a pulse at each negative spike of the differential signal. A logic circuit detects whether the digital signal switches between a first value and a second value, and whether the intermediate reset signal and the intermediate set signal include pulses lasting longer than a threshold. The logic produces a set correction signal and a reset correction signal. The logic circuit produces a corrected set signal and a corrected reset signal. An output circuit produces an output signal based on the corrected set signal and the corrected reset signal.

  • Patent number: 12009743
    Abstract: A method of operating an electronic converter is provided in which a switching activity of a switching stage of the electronic converter is active or inactive based on a control signal, and the method includes operating the electronic converter, alternatively, in a first or a second mode. In the first mode, the status signal is initially asserted and is de-asserted in response to an amplitude of the input sensing signal failing to reach a first reference threshold value. In the second mode, the status signal is initially de-asserted and an auxiliary power supply signal is periodically varied with a variation period. After a time interval equal to the variation period, a comparison signal is asserted in response to an amplitude of the sensed signal reaching a second reference threshold value. The status signal is asserted based on conditions of the comparison signal and the periodically varying auxiliary power supply signal.
