An exemplary embodiment includes a method that receives a plurality of mathematical expressions having a plurality of input variables. The mathematical expressions can then be parsed, checked for proper syntax and one or more abstract syntax trees can be formed. Next, the input variables are then assigned to input ports of the dynamically configurable arithmetic unit. Then using the parsed mathematical expressions with the assigned input ports, a list of operations to be performed by the dynamically configurable arithmetic unit are determined. And lastly, an interface to the dynamically configurable arithmetic unit is generated using in part the variable-to-input port assignments and the list of operations.
