  • Patent number: 9779044
    Abstract: A data processor system includes a local memory, a processor core, and an extent monitor. The local memory stores a block of data at a task memory location that is exclusive to a particular task during a duration of time. The processor core accesses the task memory location of the local memory during the execution of the particular task, and modifies to the block of data stored in the task memory location. The extent monitor monitors a write operation the processor core to the local memory to determine a first most-extreme address of the task memory location modified by the execution of the particular task during the duration of time. The processor core also executes a write back instruction to write back to a shared memory location less than the entire block of data based upon the most-extreme address.

  • Patent number: 9776853
    Abstract: A mechanism for reducing stiction in a MEMS device by decreasing surface area between two surfaces that can come into close contact is provided. Reduction in contact surface area is achieved by increasing surface roughness of one or both of the surfaces. The increased roughness is provided by forming a micro-masking layer on a sacrificial layer used in formation of the MEMS device, and then etching the surface of the sacrificial layer. The micro-masking layer can be formed using nanoclusters. When a next portion of the MEMS device is formed on the sacrificial layer, this portion will take on the roughness characteristics imparted on the sacrificial layer by the etch process. The rougher surface decreases the surface area available for contact in the MEMS device and, in turn, decreases the area through which stiction can be imparted.

  • Patent number: 9778668
    Abstract: A circuit includes an evaluation node through which current flows from a voltage source node to a sensed switch when the sensed switch is closed. First and second control switches are disposed between the voltage source node and the evaluation node to switch between first and second current paths for the current. The current passes through the first control switch when flowing along the first current path. The second control switch is coupled to a control terminal of the first control switch to deactivate the first control switch and allow the current to flow through the second current path. Multiple passive circuit elements are configured to establish first and second current levels for the current. The passive circuit elements are disposed between the voltage source node and the evaluation node in a circuit arrangement in which no current path to ground is present when the sensed switch is open.

  • Patent number: 9775034
    Abstract: Distance-based authentication is provided for mitigating undesirable interaction and/or attacks upon ranging systems, such as those involving vehicle entry or secure payment. As may be implemented in accordance with one or more embodiments, a leading edge of one or more pulses in a waveform of a signal is obscured as part of distance-based authentication. For instance, noise may be generated via a noise modulation circuit and combined with some or all of a leading edge of a pulse. Distance-based authentication is provided by transmitting a signal with a waveform having the obscured portion of the leading edge, which operates to mitigate detection of the polarity of the leading edge or otherwise of the leading edge itself.

  • Patent number: 9774299
    Abstract: An embodiment of an amplifier system includes a modifiable signal adjustment device with an RF signal adjustment circuit coupled between first and second nodes. The RF signal adjustment circuit includes an adjustable phase shifter and an adjustable attenuator coupled in series with each other. The device also includes a memory and a controller circuit. The controller circuit retrieves a phase shift value and an attenuation value from the memory. The controller circuit then controls the adjustable phase shifter to apply a phase shift corresponding to the phase shift value to an input RF signal received at the first node, and controls the adjustable attenuator to apply an attenuation corresponding to the attenuation value to the input RF signal. Applying the phase shift and the attenuation results in an output RF signal at the second node.

  • Patent number: 9772963
    Abstract: An interrupt management system for managing multiple interrupts includes a timer and an interrupt management sub-system. The interrupt management sub-system receives first and second interrupts, determines the first interrupt to be a real-time interrupt and the second interrupt to be a non-real-time interrupt, initializes the timer for a predetermined time period on reception of the first interrupt, and determines whether the second interrupt is either a maskable or non-maskable interrupt. The interrupt management sub-system transmits the first interrupt to an interrupt controller, en-queues the second interrupt during the predetermined time period, and transmits the second interrupt to the interrupt controller after the predetermined time period when the second interrupt is a maskable interrupt. The interrupt management sub-system transmits the second interrupt to the interrupt controller during the predetermined time period when the second interrupt is a non-maskable interrupt.
