  • Patent number: 11307767
    Abstract: A system-on-chip (SoC) includes a system memory, a memory controller, and a memory management system coupled therebetween. The memory management system is configured to receive, from the memory controller, a first control signal that is indicative of a memory operation associated with the system memory, and output and provide a second control signal to the system memory to control an execution of the memory operation. The second control signal is outputted such that when the memory operation corresponds to a first read operation, the first read operation is executed with the system memory, and when the memory operation corresponds to a first write operation, a second read operation is executed with the system memory followed by the first write operation. Thus, the memory management system prevents memory corruption of the system memory when an asynchronous reset event is detected in the SoC.

  • Patent number: 11299405
    Abstract: A purification apparatus includes a radio frequency (RF) signal source that generates an RF signal, first and second electrodes, and a conduit. The first electrode receives the RF signal and converts it into electromagnetic energy that is radiated by the first electrode. The conduit includes input and output ports and a chamber. The input and output ports are in fluid communication with the chamber, and the chamber is configured to receive an electrodeless bulb. The chamber is defined by first and second boundaries that are separated by a distance that is less than the wavelength of the RF signal so that the chamber is sub-resonant. The first electrode is physically positioned at the first boundary, and the second electrode is physically positioned at the second boundary. The first and second electrodes and the chamber form a structure that capacitively couples the electromagnetic energy into an electrodeless bulb within the chamber.

  • Patent number: 11301607
    Abstract: Testing of integrated circuitry, wherein the integrated circuitry includes a flip-flop with an asynchronous input, so that during performance of asynchronous scan patterns, glitches are avoided. Combinatorial logic circuitry delivers a local reset signal to the asynchronous input independent of an assertion of an asynchronous global reset signal. A synchronous scan test is performed of delivery of the local reset signal from the combinatorial logic circuitry while masking delivery of any reset signal to the asynchronous input of the flip-flop. An asynchronous scan test is performed of an asynchronous reset of the flip-flop with the asynchronous global reset signal while masking delivery of the local reset signal to the asynchronous input of the flip-flop.

  • Patent number: 11295151
    Abstract: Embodiments provide line-based feature generation for vision-based driver assistance systems and methods. For one embodiment, a feature generator includes a circular buffer and a processor coupled to an image sensor. The circular buffer receives image data from the image sensor and stores N lines at a time of an image frame captured by the image sensor. The N lines of the image frame are less than all of the lines for the image frame. The processor receives the N lines from the circular buffer and stores one or more features generated from the N lines in a memory. Iterative blocks of N lines of image data are processed to complete processing of the full image frame, and multiple frames can be processed. The generated features are analyzed by a vision processor to identify, classify, and track objects for vision-based driver assistance and related vision-based assistance actions.
