摘要： 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.

In order to implement the connection topology even in the case of piling up a plurality of LSIs one after another, in particular, a programmable memory element for designating respective penetration-electrode ports for use in transmit, or for us in receive, and address allocation of the respective penetration-electrode ports is mounted in stacked LSIs.

摘要： A speed performance measurement circuit that may perform speed performance measurement is provided between a first logic circuit and a second logic circuit. The speed performance measurement circuit includes a first flip flop that stores first data, a first delay circuit that delays the first data and generates second data, and a second flip flop that stores the second data. Furthermore, the speed performance measurement circuit includes a first comparator circuit that compares output of the first flip flop to output of the second flip flop, and a third flip flop that stores output data from the first comparator circuit in accordance with timing of the first clock signal. Data in a normal path is compared to data in a path delayed by a certain time to measure speed, and power voltage of a circuit is determined based on such comparison. Thus, change in speed with respect to power voltage in a critical path can be measured.
