Synthesizing interconnect-efficient low density parity check codes
Error correcting codes are widely used in communication and storage applications. Codec complexity has usually been measured with a software implementation in mind. A recent hardw...

Multiple constant multiplication by time-multiplexed mapping of addition chains
An important primitive in the hardware implementations of linear DSP transforms is a circuit that can multiply an input value by one of several different preset constants. We prop...

Efficient detection and exploitation of infeasible paths for software timing analysis
Accurate estimation of the worst-case execution time (WCET) of a program is important for real-time embedded software. Static WCET estimation involves program path analysis and ar...

Cross Entropy: A New Solver for Markov Random Field Modeling and Applications to Medical Image Segmentation
This paper introduces a novel solver, namely cross entropy (CE), into the MRF theory for medical image segmentation. The solver, which is based on the theory of rare event simulati...

Quadratic programming relaxations for metric labeling and Markov random field MAP estimation
Quadratic program relaxations are proposed as an alternative to linear program relaxations and tree reweighted belief propagation for the metric labeling or MAP estimation problem...
