SYSTOLIC ARRAY FOR MATRIX TRIANGULARIZATION AND BACK-SUBSTITUTION

Methods for matrix processing and devices therefor are described. A systolic array in an integrated circuit is coupled to receive a first matrix as input; and is capable of operating in two modes, namely a triangularization mode and a back-substitution mode. The systolic array, when in a triangularization mode, is coupled to triangularize the first matrix to provide a second matrix. When in a back-substitution mode, the systolic array is coupled to invert the second matrix.
