Automatic code generation for executing tiled nested loops onto parallel architectures
This paper presents a novel approach for the problem of generating tiled code for nested for-loops using a tiling transformation. Tiling or supernode transformation has been widel...

A Study of Implicit Data Distribution Methods for OpenMP Using the SPEC Benchmarks
In contrast to the common belief that OpenMP requires data-parallel extensions to scale well on architectures with non-uniform memory access latency, recent work has shown that it ...

Rate-Based versus Distortion-Based Optimal Joint Source-Channel Coding
- We consider a joint source-channel coding system that protects an embedded wavelet bitstream against noise using a finite family of channel codes with error detection and error c...

Message passing algorithms and improved LP decoding
Linear programming decoding for low-density parity check codes (and related domains such as compressed sensing) has received increased attention over recent years because of its p...

Additive vector decoding of transform coded images
—In a standard transform coding scheme of images or video, the decoder can be implemented by a table-lookup technique without the explicit use of an inverse transformation. In th...
