Today the presence of sub-word parallelism (SWP) is quite general in several architectures such as in general purpose processors or in the functional units of connected processing elements of application specific architectures. A skillful utilization of sub-word parallelism, i.e. the parallel execution of operations on data with low word width (sub-words), has a strong impact on the system performance...
In this paper we derive an efficient realization of the edge detection algorithm on a target architecture with parallelism on two levels. Our target architecture is a processor array where parallelism is achieved 1) within the processing elements by sub-word parallelism (SWP) and 2) within the processor array by an arrangement of several processing elements. We exploit the parallelism on both levels...
Ellipsometry and surface plasmon-polariton resonance were used to measure both the thickness, d, and refractive index, N, of tert-butylcalix[n]arene (n=4, 6 and 8) films, as well as the effect of the adsorption of benzene, toluene and chloroform on these parameters. The refractive index values were found to lie in the range 1.56-1.58. Exposure to benzene (chloroform) vapour increased N by 0.01-0...
