Computer architecture researchers evaluate key areas such as pipelining, organization, instruction issue, branching, and exception handling when considering asynchronous and synchronous design and implementation trade-offs. Asynchronous or clockless designs are considered as an alternative to conventional synchronous digital system design. The major advantages of asynchronous are low power cons...

Recent research has shown that implementations with variable execution timing may allow attackers to extract secret cryptographic keys stored on the device. Timing variances can occur due to implementation choices (e.g. data-dependent branches) or due to the internal architecture of the processor core (e.g. cache lines). In order to overcome this problem one needs to find alternative implementa...

Embedded systems are everywhere, from home appliances to critical systems such as medical devices. They usually have associated timing constraints that need to be verified for the implementation. Here, we use an untimed bounded model checker to verify timing properties of embedded C programs. We propose an approach to specify discrete time timing constraints using code annotations. The annotate...

In this contribution, we investigate the influence of timing errors on the performance of a multicarrier codedivision multiple-access (MC-CDMA) system. We show that a constant timing offset introduces no degradation of the signal-to-noise ratio (SNR) at the input of the decision device as it can be compensated without loss of performance. On the other hand, in the presence of timevarying timing...

In this paper, we study position-dependent timing shifts and timing resolution in position sensitive avalanche photodiodes (PSAPDs) and their effects on the coincidence window used in positron emission tomography (PET) systems using these devices. There is a delay in PSAPD signals that increases as the excitation position moves from the corner to the center of the device and the timing resoluti...

This paper presents the design of a MEMS capacitive vibration-to-electricity energy converter with integrated mechanical switches for precise timing control. Integrated lateral mechanical contact switches have the advantage of zero leakage current, low energy consumption and synchronous operation. The new design can provide an output power of 31μW at a 40V output voltage from the targeted vibra...

A memristor is a two-terminal electronic device whose conductance can be precisely modulated by charge or flux through it. Here we experimentally demonstrate a nanoscale silicon-based memristor device and show that a hybrid system composed of complementary metal-oxide semiconductor neurons and memristor synapses can support important synaptic functions such as spike timing dependent plasticity....
