Computer arithmetic [4] or digital arithmetic is the science that combines mathematics with computer engineering and deals with representing integers and real values in digital systems and efficient algorithms for manipulating such numbers by means hardware circuitry and software routines. Arithmetic operations on pairs of numbers x and y include addition (s = x + y), subtraction (d = x – y), multiplication (p = x × y), and division (q = x/y). Subtraction and division can be viewed

In this paper, a new multiplier-less algorithm is proposed for the design of perfect- reconstruction linear-phase (PR LP) filter banks by using multiplier-less lattice structures. The coefficients in the multiplication operations have been replaced with limited number of additions and the computational complexity is reduced significantly. The property of perfection reconstruction, however, is preserved regardless the multiplier-less approximation of lattice structures in the factorization of

An efficient simplification procedure of the optical flow (OF) algorithm as well as its hardware implementation using the field programmable gate array (FPGA) technology is presented. The modified algorithm is based on block matching of subsets of successive frames, and exploits one-dimensional representation of subsets as well as the adaptive adjustments of their sizes. Also, an l1-norm-based correlation function requiring no multiplication/division operations is used. As a result, it was

In order to deal with the inefficiency of trational serial tool path algorithms and incompatibility issues on the heterogeneous hardware platforms, this paper suggests a tool path planning method based on CPU-GPU(Central Processing Unit-Graphic Processing Unit) heterogeneous parallel computing. The method contra poses NURBS(Non-Uniform Rational B-Splines) surface which is abstracted as a matrix multiplication on the principle of isoparametric line tool path planning method. Then a parallel
