Abstract
Fixed-point simulation results are used for the performance measure of inverting matrices using the Cholesky decomposition. The working space is reduced significantly by grouping signals using hardware sharing and a variable position of the radix point. The hardware cost of the functional units is reduced by 25% when compared to floating-point.
