Abstract

See full text

An interface to a dynamically configurable arithmetic unit can include data alignment modules, where each data alignment module receives input variables being associated with one or more arithmetic expressions. The interface can include multiplexers coupled to the data alignment modules, wherein a data alignment module has outputs coupled to a first multiplexer. The first multiplexer can have a selection line and an output coupled to an input port of the dynamically configurable arithmetic unit. The interface can include a second multiplexer having input instructions and the selection line, where each instruction is associated with one of the arithmetic expressions and has an operation to be performed by the dynamically configurable arithmetic unit. The second multiplexer is configurable to provide selected ones of the input instructions to the dynamically configurable arithmetic unit through an output of the second multiplexer responsive to the selection line.
