Abstract
Approaches for Cholesky decomposition of a matrix are described. A first circuit is configured to generate an inverse square root of an input value. A second circuit is configured to generate a product of a value output by the first circuit and provided at a first input and a value provided at a second input. A third circuit is configured to generate a difference between a value provided at the first input and a value provided at the second input of the third circuit. The first input of the third circuit is coupled to the output of the second circuit. A control circuit is configured to iteratively distribute a plurality of values of the matrix and the outputs of the first, second, and third circuits to the inputs of the first, second, and third circuits such that the Cholesky decomposition of the matrix is output by the third circuit.
