Accuracy Configurable Modified Booth Multiplier Using Approximate Adders
2015 IEEE International Symposium on Nanoelectronic and Information Systems, 2015High speed multipliers are an essential component for real time multimedia applications. Majority of these applications can tolerate some amount of error in output of the multiplier and error permissible can dynamically vary within an application. This paper presents architecture for an accuracy configurable modified Booth multiplier (ACMBM) using ...

Low-power Accuracy-configurable Carry Look-ahead Adder Based on Voltage Overscaling Technique
IEEE International Symposium on Quality Electronic Design, 2020In this paper, a low-power accuracy-configurable block-based Carry Look-ahead Adder (AC-CLA) is proposed. The structure employs the voltage over scaling and number of approximate blocks as the approximation knobs for improving the energy consumption as ...

A microscope configuration for nanometer 3-D movement monitoring accuracy
Micron, 2011In this paper we present a new microscopy configuration based upon temporal tracking of a secondary reflected speckle by imaging the speckle through properly defocused optics. The configuration is used to monitor three-dimensional (3-D) spontaneous contraction of rat cardiac muscle cells while achieving nanometer tracking accuracy at a rate of 30 ...

Navigational range lights: effect of stimulus configuration on alignment accuracy
Ergonomics, 1995The use of range lights in nautical navigation involves the visual determination of the vertical alignment of two points of light, in order to indicate the centre of the channel. In two experiments it is shown that this vernier alignment task is more accurate if illuminated linear stimuli are used as range lights.

TDOA positioning accuracy performance evaluation for arc sensor configuration
2018 Systems of Signals Generating and Processing in the Field of on Board Communications, 2018In this paper we present time difference of arrival (TDOA) positioning accuracy performance evaluation for the case, when sensors are arranged in arc configuration. Performance evaluation is implemented through simulation model including TDOA system and link level model subsystems.

Accuracy-configurable approximate multiplier with error detection and correction
TENCON 2015 - 2015 IEEE Region 10 Conference, 2015Real-time multimedia applications which demand very low decoding delays are increasing day-by-day. To address this challenge, in error-resilient applications, many approximate computing architectures for delay critical units have been proposed. In this paper, we propose an architecture for an approximate multiplier, accuracy of which can be configured ...
