Abstract
Objects of the invention are to minimize power consumption while maintaining the required information processing capabilities of an LSI chip by supplying multiple voltages to the LSI chip such that its circuit blocks receive necessary voltages and to prevent an increase in the chip area of the LSI chip and performance degradation of signal wires, which may result from the supply of the multiple voltages, by reducing the number of power supply wires. In an LSI chip to which two voltages are supplied, high voltage wires are more densely spaced than low voltage wires. By selectively applying voltages based on circuit block performance, it is possible to reduce power consumption while maintaining the amount of information processed by the LSI chip.
