This paper introduces a plane array with single high-speed CMOS camera motion parameters for the collection of projectile testing technology. The system employs linear laser, Fresnel lens and optical fiber array to form the Optical structure. It uses a single high-speed CMOS area array camera and special data image processing software to collect and calculate image motion parameters. The paper describes...
This paper presents a high performance parallel formulation for 1-D FFT based on transpose algorithm. The parallel scheme of FFT trades off some efficiency for a more consistent level of parallel performance. It involves matrix transposition, and a new in-place transposing algorithm is introduced into the parallel matrix transposition to improve the efficiency. Depending on the size of the input n,...
This paper presents a in-place cycle-reducing method for multidimensional arrays transposition in local memory to reduce the memory R/W operations. The resulting method can significantly reduce the number of subcycles (also called following-cycles) and that of memory operations for square arrays. Taking square array 256 by 256 for example, the number of subcycles used by current available best algorithm...
