SYSTOLIC ARRAY IMPLEMENTATION OF THE SQUARE-ROOT CHANDRASEKHAR FILTER

Abstract

We have obtained a parallel algorithm for the Chandrasekhar filter for estimation in constant parameter state space models. The parallel Chandrasekhar filter can be expressed in terms of three distinct elementary operations which can be performed in parallel. The parallel Chandrasekhar filter is mapped systematically on rectangularly connected systolic arrays consisting of three types of simple processors each of which performs the elementary operations.
