  • Patent number: 8982899
    Abstract: An apparatus comprises a number of sub-systems and a control interface operably coupled to sub-systems for routing data therebetween. A strobe generation function is operably coupled to the control interface and configured to generate a plurality of different strobe signals to differentiate between different intended receiving devices. Thus, different strobe signals may be multiplexed onto a single control interface link, based on a pulse width or voltage magnitude characteristics of the respective strobe signals. A strobe decoder function is operably coupled to the control interface and configured to decode a plurality of different strobe signals to differentiate between triggering sub-systems on receiving devices.

  • Patent number: 8984344
    Abstract: During a debug mode of operation of a data processor it is determined whether a data access request is to a stack of the data processor. If not, a data trace message based on the data access request is generated for transmission to a debugger so long as an address being accessed by data access request meets a predefined address range criteria. Otherwise, if the data access request is to the stack of the data processor, a data trace message based on the data access request is prevented from being generated for transmission to the debugger regardless the predefined address range criteria.

  • Patent number: 8977790
    Abstract: An embodiment of an electronic system includes a processing element, a bus controller, and a peripheral module. The processing element executes machine readable code for performing a data transfer of an x-bit wide data value between the processing element and the peripheral module. Performing the data transfer includes providing a processing element-provided address corresponding to a y-bit wide data register of the peripheral module, where y is less than x. The bus controller receives the processing element-provided address, and in response, performs a series of multiple data transfers with the peripheral module. This includes providing a first peripheral address for a first data transfer of the series, and providing at least one different peripheral address for at least one other data transfer of the series. The peripheral module maps the first peripheral address and the at least one different peripheral address to the y-bit wide data register.

  • Patent number: 8978004
    Abstract: A layout of a standard cell is created by prioritizing routability characteristics of the standard cell layout. The routability characteristics are prioritized so that the characteristics that are more likely to enhance routing efficiency are emphasized in the cell layout. The prioritization of the routability characteristics can be indicated by a set of weights, with each weight in the set indicating the priority of a corresponding routability characteristic of the standard cell layout. The weights can be used to calculate a weighted sum of the routability characteristics of the standard cell, thereby providing a way to efficiently compare the routability of different standard cell layouts.

  • Patent number: 8976035
    Abstract: Embodiments of systems and methods include a sensor subsystem (e.g., within a container-mounted device) that produces a sensor output, and a processing system that implements a state machine. Upon entry into a first state, the processing system starts a timer, and while in a second state, the processing system waits for a specific sensor output value to be received. The processing system transitions from the first state to the second state upon expiration of the timer, and the processing system transitions from the second state to the first state when the sensor output corresponds to the specific sensor output value. When the state machine is in the second state, the output device produces a human-perceptible indicia configured to prompt a human user to perform an action that is likely to cause the sensor to produce the sensor output that corresponds to the specific sensor output value.

  • Patent number: 8975926
    Abstract: A comparator used in a clock signal generation circuit compares two input signals and generates an output signal. The comparator has first and second input transistors coupled to the input signals. First and second hysteresis transistors are coupled between the input transistors and an output stage of the comparator, and apply hysteresis to a comparison of the input signals. First and second hysteresis control transistors are coupled between the input transistors and the hysteresis transistors to isolate the hysteresis transistors from the input transistors under control of a hysteresis enable signal. The comparator is operable in a first mode or a second mode based on a hysteresis enable signal. In the first mode the comparator applies hysteresis to the comparison of the input signals and in the second mode, compares the input signals without hysteresis.
