Recently, Narozny et al [1] proposed a new viewpoint in variable high-rate transform coding. They showed that the problem of finding the optimal 1-D linear block transform for a ...
In this paper, general guidelines and specific algorithms for code transformations between breadth-first (BF) and depth-first (DF) linear quadtrees are proposed. Each algorithm ha...
We demonstrate Spiral, a domain-specific library generation system. Spiral generates high performance source code for linear transforms (such as the discrete Fourier transform and ...
