摘要： An apparatus for processing data 2 is provided with a time-to-digital converter 18 which serves to measure signal processing delay through one or more signal paths through a processing stage. This measured delay generates a delay value representing a plurality of instances of the signal processing delay which have been measured. Analysis is performed under software control to estimate a worst case signal processing delay through the processing stage based upon the delay values which have been generated. An adjustment of the operating parameters, such as supply voltage and clock frequency, of the apparatus is made to provide a timing margin through the processing stage sufficient to satisfy the worst case signal processing delay which has been estimated without an excessive margin.

摘要： A true random number generator comprises a ring oscillator which is triggered to start oscillating in a first mode of oscillation at an oscillation start time. The first mode of oscillation will eventually collapse to a second mode of oscillation dependent on thermal noise. A collapse time from the oscillation start time to the time at which the oscillator collapses to the second mode is measured, and this can be used to determine a random number. The TRNG can be synthesized entirely using standard digital techniques and is able to provide high randomness, good throughput and energy efficiency.

摘要： Synchronisation circuitry 2 comprises a first dynamic circuit stage 4 generating a first stage state signal which is pulse amplified by pulse amplifying circuitry 8 to generate a pulse amplified signal. The pulse amplified signal is supplied to a second dynamic circuit stage 6 where it is used to control generation of a second stage state signal. The pulse amplifying circuitry 8 comprises a chain of serially connected skewed inverters 20, 22. The action of the pulse amplifying circuitry 8 is to reduce the probability of metastability in the output of the second dynamic stage 6.
