Abstract:
1. An apparatus for calculating coefficients of a Cholesky decomposition of a matrix, the apparatus comprising: a multiplicity, N, of multiplication accumulation (MAC) cells to be connected together in series, wherein each MAC cell includes an accumulation input, an accumulation output, a return input, a return output, and a coefficient input, wherein the accumulation output of a previous (p a diagonal cell to be connected to the multiplicity of MAC cells, wherein the diagonal cell includes an accumulation input, a result output, a return input, a return output, and a coefficient input, wherein the accumulation input of the diagonal cell is to be connected to the accumulation output of the N wherein coefficients of the Cholesky decomposition are to be coupled to return and coefficient inputs of at least one of said MAC cells and to the coefficient input of the diagonal cell.
