Abstract: An integrated circuit is provided with error detection circuitry and error repair circuitry. Error tolerance circuitry is responsive to a control parameter to selectively disable the error repair circuitry. The control parameter is dependent on the processing performed within the circuit. For example, the control parameter may be generated in dependence upon the program instruction being executed, the output signal value which is in error, the previous behavior of the circuit or in other ways.

Abstract: A system on chip (102) comprising a plurality of logically homogeneous processor cores (104), each processor core comprising processing circuitry (210) to execute tasks allocated to that processor core, and task scheduling circuitry (202) configured to allocate tasks to the plurality of processor cores. The task scheduling circuitry is configured, for a given task to be allocated, to determine, based on at least one physical circuit implementation property associated with a given processor core, whether the given task is allocated to the given processor core.

Abstract: The present disclosure provides a method and apparatus for communicating between dice of an inductively-coupled 3D integrated circuit (3D-IC). A transmit resonant circuit at a transmit die is inductively coupled to a first receive resonant circuit at a first receive die, and to a second receive resonant circuit at a second receive die. The resonant circuit at the targeted receive die is tuned to the frequency of resonance of the transmit resonant circuit, while the resonant circuit at the untargeted receive die is detuned, resulting in lower power consumption for a given bit error rate at the targeted die.

Abstract: An integrated circuit includes a first circuit and a power meter coupled to the first circuit at selected proxy locations. The power meter includes circuitry for generating toggle data, such as signal transitions or signal levels, from signals at the proxy locations and combiner circuitry for combining the toggle data in a first time window with a set of weight value to produce a measure of power usage in the first circuit. The proxy locations and weight values are selected automatically based on simulated or emulated signals from a larger set of locations in the first circuit and associated power usage in the first circuit.

Abstract: An apparatus and method for detecting a change in electrical properties in a system is disclosed. Embodiments of the disclosure enable the detection of a change in electrical properties in a system by, in response to a load generated on a power delivery network power in at least part of the system, measuring noise induced in the power delivery network in response to the load. Based on the measured noise, a dynamic-response property of the power delivery network is determined and the dynamic-response property is compared to a stored reference dynamic-response property of the power delivery network based on a predetermined load. In the event of a difference between the dynamic-response property and the reference dynamic-response property, a response to the event is triggered to indicate tampering with the power delivery network.

Abstract: Various implementations described herein are directed to a device with a voltage-controlled oscillator that receives an enable signal, receives a reset signal, and provides internal pulse signals including one or more coarse internal pulse signals and multiple fine internal pulse signals. The device may have a coarse sampler that receives the one or more coarse internal pulse signal and provides a coarse sampled output signal. The device may have a fine sampler that receives the multiple fine internal pulse signals and provides a fine sampled output signal.

Abstract: In a particular implementation, a method includes: providing a first voltage to a word-line coupled to a first transistor device; providing a second voltage to a bit-line coupled to the first transistor device; providing a third voltage to a source-line coupled between a programmable resistive device and a voltage control element. Also, the first transistor device is coupled to the programmable resistive device and the voltage control element, where the programmable resistive device is configured to replace a first data value by writing a second data value in the programmable resistive device. Moreover, in response to a voltage difference across the programmable resistive device exceeding a particular threshold, limiting the voltage difference by one of reducing the second voltage on the bit-line or increasing the third voltage on the source-line.
