A circuit and method degrades throughput of floating point operations within a computing system. At the time of manufacture a preprogrammed value is stored. This may be done, for example, using fusible links, separate metal layers, internal bonding pad selection, EPROM/OTP memory cells, ion milling, laser evaporation and external programming pins. When a floating point processor processes a floating point operation, operation of a main processor is delayed an amount corresponding to the preprogrammed value. For example, when the floating point processor processes a floating point operation, a counter begins to count. Operation of the main processor is delayed until the counter has counted to a number equal to the preprogrammed value. Upon the counter completing counting to a number equal to the preprogrammed value, normal operation of the main processor is resumed.
