摘要: Systems, methods and program codes are provided for testing multi-core processor chip structures. Individual processor core power supply voltages are provided through controlling individual power supplies for each core, in one aspect to ensure that one or more cores operate at clock rates in compliance with one or more performance specifications. In one example, a first power supply voltage supplied to a first processing core differs from a second core power supply voltage supplied to a second processing core, both cores operating in compliance with a reference clock rate specification. Core power supply voltages may be selected from ordered discrete supply voltages derived by progressively raising or lowering a first supply voltage, optionally wherein the selected supply voltage also enables the core to operate within another performance specification.

摘要: Systems, methods and program codes are provided for selectively adjusting multi-core processor chip structure individual processor core power supply voltages through controlling individual power supplies for each core, in one aspect to ensure that one or more cores operate at clock rates in compliance with one or more performance specifications. Nominal power supply voltage is supplied to a first processing core, and a second core power supply voltage greater or lower than the nominal power supply voltage is supplied to a second processing core, both cores operating in compliance with a reference clock rate specification. The second power supply voltage may be selected from ordered discrete supply voltages derived by progressively lowering the nominal supply voltage, optionally wherein the selected supply voltage also enables the second core to operate within another performance specification.

摘要: System and method are provided for continually monitoring reliability, or aging, of a digital system and for issuing a warning signal if digital system operation degrades past a specified threshold. The technique includes implementing a ring oscillator sensor in association with the digital system, wherein logic and/or device percent composition of the ring oscillator sensor mirrors percent composition thereof within the digital system. Counter logic is coupled to the ring oscillator sensor for converting outputted count signals to an oscillation frequency, and control logic is coupled to the counter logic for periodically evaluating oscillation frequency of the ring oscillator sensor and generating a warning signal indicative of reliability degradation if at least one of: (i) a measured or estimated oscillation frequency is below a warning threshold frequency; or (ii) a measured or estimated rate of change in a difference between measured oscillation frequencies exceeds an acceptable rate of change threshold.

摘要: In a random number generator, a first converter converts a first analog noise signal into a random digital clock signal and a second converter samples a second analog noise signal asynchronous to the first analog noise signal in response to the random digital clock signal and generates a random digital number stream. In one aspect, a random number generator output block samples the second converter random digital number stream in response to the random digital clock signal and generates a random number generator block output. In another aspect a pseudo noise source state machine generates the random digital clock signal in response to a first seed generated from the first analog noise signal, a second seed from process variation digital amplifier, and a past machine state.
