Exploiting GPU On-chip Shared Memory for Accelerating Schedulability Analysis
Embedded electronic devices like mobile phones and automotive control units must perform under strict timing constraints. As such, schedulability analysis constitutes an important phase of the design cycle of these devices. Unfortunately, schedulability analysis for most realistic task models turn out to be computationally intractable (NP-hard). Naturally, in the recent past, different techniques have been […]

A local diffusion wavelet approach for scattered data registration based on GPU
In order to register partly overlapped data clouds measured from different view points, a multi-resolution registration method based on local diffusion wavelet features was proposed. Firstly, we detect multi-scale salient points from large number of original data, and a subset of data was extracted within a neighbourhood around each salient point. Secondly, diffusion wavelet decomposition […]
