| 1. A voltage regulation apparatus for use on an integrated circuit device, comprising:
an automatic process identifier configured to identify a process split of the device;
a memory circuit coupled to the automatic process identifier, the memory circuit configured to store data comprising target
voltages for different process splits;
a processing unit;
a power supply; and
a voltage regulator circuit coupled to the memory circuit and to the power supply, the regulator configured to adjust the
power supply value according to the automatic process identifier and the memory circuit, the adjusted power supply causing
the processing unit to operate substantially at a target frequency.
