Abstract
A data processing element includes an input unit configured to provide instructions for scalar, vector and array processing, and a scalar processing unit configured to provide a scalar pipeline datapath for processing a scalar quantity. Additionally, the data processing element includes a vector processing unit coupled to the scalar processing unit and configured to provide a vector pipeline datapath employing a vector register for processing a one-dimensional vector quantity. The data processing element further includes an array processing unit coupled to the vector processing unit and configured to provide an array pipeline datapath employing a parallel processing structure for processing a two-dimensional vector quantity. A method of operating a data processing element and a MIMO receiver employing a data processing element are also provided.
