  • Patent number: 8020137
    Abstract: A design structure for a circuit that selectively connects an integrated circuit to elements external to the integrated circuits. The circuit includes and input/output element that selectively connects an input/output pin as a function of a power requirement or a signal bandwidth requirement of the integrated circuit. The input/output element includes one or more switching devices that connect the input/output pin to an external element, such as a power supply or external signal path. The input/output element also includes one or more switching devices that connect the input/output pin to an internal element, such as a power network or internal signal line.

  • Patent number: 8010813
    Abstract: Disclosed is a design structure for an associated first system for extending product life of a second system in the presence of phenomena that cause the exhibition of both performance degradation and recovery properties within system devices. The first system includes duplicate devices incorporated into the second system (e.g., on a shared bus). These duplicate devices are adapted to independently perform the same function within that second system. Reference signal generators, a reference signal comparator, a power controller and a state machine, working in combination, can be adapted to seamlessly switch performance of that same function within the second system between the duplicate devices based on a measurement of performance degradation to allow for device recovery. A predetermined policy accessible by the state machine dictates when and whether or not to initiate a switch.

  • Patent number: 7949978
    Abstract: A design structure integrated circuit (IC) system architectures that allow for the reduction of on-chip or across-chip transient noise budgets by providing a means to avoid simultaneous high current demand events from at least two functional logic blocks, i.e., noise contributors, are disclosed. Embodiments of the IC system architectures include at least one noise event arbiter and at least two noise contributor blocks. A method of scheduling on-chip noise events to avoid simultaneous active transient noise events may include, but is not limited to: the noise event arbiter receiving simultaneously multiple requests-to-operate from multiple noise contributors; the noise event arbiter determining when each noise contributor may execute operations based on a pre-established dI/dt budget; and the noise event arbiter notifying each noise contributor as to when permission is granted to execute its operations.

  • Patent number: 7941772
    Abstract: Method for correcting timing failures in an integrated circuit and device for monitoring an integrated circuit. The method includes placing a first and second latch near a critical path. The first latch has an input comprising a data value on the critical path. The method further includes generating a delayed data value from the data value, latching the delayed data value in the second latch, comparing the data value with the delayed data value to determine whether the critical path comprises a timing failure condition, and executing a predetermined corrective measure for the critical path.

  • Publication number: 20110099527
    Abstract: A method configures a plurality of circuit elements for execution of an application in a first configuration. The method monitors the execution of the application on the plurality of circuit elements to produce monitoring information, using a computerized device, and stores the monitoring information in a storage structure. The method selectively communicates the monitoring information to an external element separate from the computerized device. The external element transforms the first configuration into a second configuration based on the monitoring information. The computerized device receives the second configuration from the external element and reconfigures the plurality of elements into the second configuration.

  • Patent number: 7904872
    Abstract: Disclosed is a system-on-chip (SOC) structure that allows for automated integration of multiple intellectual cores. The SOC structure incorporates a plurality of cells connected to a common bus on a chip. Each cell incorporates a functional core and an automated integration unit (AIU) connected to the functional core. Each AIU communicates integration information for its functional core over the common bus to the AIUs in the other cells. The exchange of information between the AIUs is controlled either by the integration units themselves or by a controller. Based on received integration information, each AIU can automatically make any required configuration adjustments for integration. Furthermore, based on this exchange of information, the functional cores can interact, as necessary, during SOC operation. Also disclosed are an associated method of forming such a SOC structure and a design structure for such an SOC structure.

  • Patent number: 7849426
    Abstract: The embodiments of the invention provide a design structure for detection and compensation of negative bias temperature instability (NBTI) induced threshold degradation. A semiconductor device is provided comprising at least one stress device having a voltage applied to its gate node and at least one reference device having a zero gate-to-source voltage. A controller is also provided to configure node voltages of the device and/or the reference device to reflect different regions of device operations found in digital and analog circuit applications. Moreover, the controller measures a difference in current between the stress device and the reference device to determine whether NBTI induced threshold degradation has occurred in the stress device. The controller also adjusts an output power supply voltage of the stress device until a performance of the stress device matches a performance of the reference device to account for the NBTI induced threshold degradation.

  • Publication number: 20100191385
    Abstract: Disclosed are a power management system and associated method that not only initiate a “greenout” to avoid the negative impact of high loads (i.e., to avoid high power cost, negative environmental impact, brownouts, and ultimately blackouts), but can also predict the initiation of such a “greenout”. Predicting the initiation of a “greenout” and communicating the prediction to one or more of the various electronic devices connected to the power grid allows the electronic device(s) to take preparatory action to avoid and/or limit any negative impact that may be caused by the “greenout”.

  • Patent number: 7619398
    Abstract: Disclosed herein is a system for controlling power supply voltage to an on-chip power distribution network. The system incorporates a programmable on-chip sensing network that can be selectively connected to the power distribution network at multiple locations. When the sensing network is selectively connected to the power distribution network at an optimal sensing point, a local voltage feedback signal from that optimal sensing point is generated and used to adjust the power supply voltage and, thus, to manage voltage distribution across the power distribution network. Additionally, the system incorporates a policy for managing the voltage distribution across the power distribution network, a means for profiling voltage drops across the power distribution network and a means for selecting the optimal sensing point based on the policy and the profile. Another embodiment of the system can further control power supply voltages to multiple power distribution networks on the same chip.
