Abstract
A control logic unit outputs a group of encoded control signals that have less redundancy than the FPU signals needed to control a floating point processor, thus requiring fewer signal lines using less area. Decoders electrically connected between the control logic unit and the floating point processor decode the control signals to provide the FPU signals. If the number of control signals is one less than the number of FPU signals, a priority encoder is used as the decoder, unless the FPU signals include a power savings signal. Otherwise a custom decoder is used. The most active signal of the group of FPU signals is selected as the signal to be eliminated when a priority encoder is used.
