  • Patent number: 12039293
    Abstract: System, method, and circuitry for generating a linker model for use by a toolchain associated with a programmable computing device. One or more regions in the memory resources available to the programmable computing devices is defined for used by an application executing on the programmable computing device. One or more sections is defined for those regions for use by the application. Resource boundaries are generated for the application based on the defined regions and the defined sections. A user is enabled to modify the defined regions or the defined sections or the generated resource boundaries. A linker model is then generated based on the available memory resources, the defined regions, the defined sections, and the generated resource boundaries. This linker model is then utilized to generate a linker script for the programmable computing device based the linker syntax compatible with a toolchain linker for the programmable computing device.

  • Patent number: 12038454
    Abstract: A MEMS inertial sensor includes a supporting structure and an inertial structure. The inertial structure includes at least one inertial mass, an elastic structure, and a stopper structure. The elastic structure is mechanically coupled to the inertial mass and to the supporting structure so as to enable a movement of the inertial mass in a direction parallel to a first direction, when the supporting structure is subjected to an acceleration parallel to the first direction. The stopper structure is fixed with respect to the supporting structure and includes at least one primary stopper element and one secondary stopper element. If the acceleration exceeds a first threshold value, the inertial mass abuts against the primary stopper element and subsequently rotates about an axis of rotation defined by the primary stopper element. If the acceleration exceeds a second threshold value, rotation of the inertial mass terminates when the inertial mass abuts against the secondary stopper element.

  • Patent number: 12040013
    Abstract: A memory array includes memory cells forming a data word location accessed in response to a word line signal. A data sensing circuit configured to sense data on bit lines associated with the memory cells. The sensed data corresponds to a current data word stored at the data word location. A data latching circuit latches the sensed data for the current data word from the data sensing circuit. A data modification circuit then performs a mathematical modify operation on the current data word to generate a modified data word. The modified data word is then applied by a data writing circuit to the bit lines for writing back to the memory cells of the memory array at the data word location. The operations are advantageously performed within a single clock cycle.

  • Patent number: 12040628
    Abstract: A bridge rectifier is controlled by control circuitry to act a “regtifier” which both regulates and rectifies without the use of a traditional voltage regulator. To accomplish this, the gate voltages of transistors of the bridge that are on during a given phase may be modulated to dissipate excess power. Gate voltages of transistors of the bridge that are off during the given phase may alternatively or additionally be modulated to dissipate excess power. The regtifier may act as two half-bridges that each power a different voltage converter, with those voltage converters powering a battery. The voltage converters may be switched capacitor voltage converters that switch synchronously with switching of the two half-bridges as they perform rectification.

  • Publication number: 20240235573
    Abstract: An integrated circuit includes a continuous time delta sigma analog-to-digital converter (CTDS ADC) and a test circuit for testing the CTDS ADC. The test circuit converts multibit digital reference data to a single-bit digital stream. The test circuit then passes the single-bit digital stream to a finite impulse response digital-to-analog converter (FIR DAC). The FIR DAC converts the single-bit digital stream to an analog test signal. The analog test signal is then passed to the CTDS ADC. The CTDS ADC converts the analog test signal to digital test data. The test circuit analyzes the digital test data to determine the accuracy of the CTDS ADC.

  • Publication number: 20240235546
    Abstract: A resettable digital stage operates when a supply voltage is higher than a threshold. A non-volatile memory stores a digital code read by a reading stage. A main power-on reset circuit generates a main reset signal controlling reset of the reading stage. A resettable volatile memory coupled to the reading stage stores a default value when reset. An auxiliary power-on reset circuit generates an auxiliary reset signal controlling reset of the volatile memory. Upon deactivation of the reset, the reading stage loads the digital code into the volatile memory. The main power-on reset circuit functions in a non-trimmed configuration response to the stored default value and in a trimmed configuration responsive to the stored digital code. The main power-on reset circuit has first and second operative thresholds which respectively fall within a first and second non-trimmed voltage range or within a first and second trimmed voltage range.
