In this paper we describe new parallel cyclic wavefront algo rithms for solving the semide nite discrete time Lyapunov equation for the Cholesky factor using Hammarling s method by the message passing para digm These algorithms are based on previous cyclic and modi ed cyclic algorithms designed for the parallel solution of triangular linear systems The experimental results obtained on an SGI Po...

This paper presents an e cient hardware algorithm for variable precision division The algorithm is based on a well known convergence algorithm however modi cations are made to allow it to e ciently handle variable precision operands The proposed al gorithm reduces the number of xed precision operation by only computing signi cant words in intermediate results Compared to previous variable preci...
