This paper proposes a self-calibrating approach for embedded RF down-conversion mixers. In the proposed approach, the output of the RF mixer is analyzed by using on-chip resources for testing and the mixer performs self-compensation for parametric defects using tuning knobs. The tuning knobs enable the RF mixer to self-calibrate for multi-parameter variations induced due to process variability. Using...
Poor visibility in foggy weather stems from the fact that particles in atmosphere scatter and absorb light from the environment and light reflected from the objects. Mathematically, de-weathering a fog degraded image is an ill posed problem and existing approaches are of high complexity and low versatility. In this paper, a novel fuzzy logic based algorithm, to de-weather fog-degraded images, is proposed...
This paper proposes a novel self-healing methodology for embedded RF Amplifiers (LNAs) in RF sub-systems. The proposed methodology is based on oscillation principles in which the Device-under-Test (DUT) itself generates the output test signature with the help of additional circuitry. The self-generated test signature from the DUT is analyzed by using onchip resources for testing the LNA and controlling...
A future provides the basic primitive through which a user in an object-oriented distributed system can achieve concurrency. It is based on the notion of being able to translate what appears to be a remote procedure call into a request for computation to be scheduled by the system. The mechanism required to make this translation is discussed. Refinements to the future mechanism allow futures to be...
