High-accuracy configuration-space faddeev calculations
Nuclear Physics A, 1990A new method for solving the bound-state configuration-space Faddeev equations is presented. This method is largely based on the (Los Alamos) spline method, but exploits the tensor structure of the resulting matrix problem. With this method accurate results can be obtained using small computers, or very accurate results using large computers.

A low latency generic accuracy configurable adder
Proceedings of the 52nd Annual Design Automation Conference, 2015High performance approximate adders typically comprise of multiple smaller sub-adders, carry prediction units and error correction units. In this paper, we present a low-latency generic accuracy configurable adder to support variable approximation modes. It provides a higher number of potential configurations compared to state-of-the-art, thus enabling

Polarimetric radiometer configurations: potential accuracy and sensitivity
IEEE Transactions on Geoscience and Remote Sensing, 1999Ocean wind speed and direction can be assessed with a polarimetric radiometer system measuring the full set of Stokes parameters. There are two fundamentally different ways of implementing the polarimetric radiometer system: polarization combining and correlation radiometer systems. Also, within each fundamental category there are significant tradeoffs.

Cross-Layer Approximate Hardware Synthesis for Runtime Configurable Accuracy
IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2021Approximate computing trades off computation accuracy against energy efficiency. The extent of approximation tolerance, however, significantly varies with a change in input characteristics and applications. We propose a novel cross-layer approach for the synthesis of runtime accuracy-configurable hardware that minimizes energy consumption at area ...

We propose an OpenMP programming environment for fine-grained approximate computing on multi-core cluster architecture with shared and accuracy-reconfigurable floating-point units (FPUs). This shared-FPUs cluster dynamically characterize FP pipeline vulnerability (FPV) and expose it as metadata to a software scheduler for reducing the cost of error ...

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 ...

Automatic Generation of Resource and Accuracy Configurable Processing Elements
ACM Transactions on Embedded Computing Systems, 2023Low-power consumption and scarce computational resources limit the computation at the edge. Besides, the approximate computing paradigm reports promising techniques for designing accelerators to deal with inherent limitations of the edge, and high-level synthesis with C++ opens the opportunity to use meta-programming for specialisable ...

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.
