<p>Provided are a programmable apparatus and a method for managing the power supply voltage thereof wherein characteristic fluctuations can be compensated for while the area overhead of a monitor circuit for detecting the characteristic fluctuations can be suppressed. For this purpose, first circuit data, which include a monitor circuit for detecting a characteristic parameter having a power supply voltage dependency, and second circuit data including a user circuit are stored into a memory circuit unit (103). Initially, the first circuit data are configured in a programmable circuit (FPGA) (101), and after the monitor circuit detects the characteristic parameter, the second circuit data, instead of the first circuit data, are configured, so that the user circuit operates. The power supply voltage when the user circuit operates is determined on the basis of a detection result of the monitor circuit.</p> |
