A voltage stacked system that includes a stack of near threshold computing (NTC) chips for achieving inter-chip communication with simple wires as interconnections is disclosed. The chips include at least two secondary supply voltages and at least a secondary ground voltage electrically coupled to the stack of the chips arranged in series. The secondary supply and ground voltages are tapped in a predefined sequence at one or more predefined access points in the stack to generate two versions of an internal voltage within each of the chips. Each of the two versions of the internal voltage is a voltage difference between respective supply voltages and ground voltages, and the two have a set voltage shift such that the chips in the stack have supply voltages overlapping with those in the neighboring chips. Optionally, the two voltages are boosted to further higher voltages as needed using charge pumps.

An information processing apparatus includes a processor configured to: store document information of a document in a predetermined storage region when processing that does not include a storing process of the document is executed on the document; display the document information stored in the predetermined storage region on a display when executing processing, the document information including at least one item of the document information, and cause a user to select an item of the document information from the at least one item of the document information; and execute processing by using the selected item of the document information.

A power regulator provides current to a processing unit. A clock distribution network provides a clock signal to the processing unit. A level-based droop detector monitors a voltage of the current provided to the processing unit and provides a droop detection signal to the clock distribution network in response to the voltage falling below a first threshold voltage. The clock distribution network decreases a frequency of a clock signal provided to the processing unit in response to receiving the droop detection signal. The level-based droop detector interrupts the droop detection signal that is provided to the clock distribution network in response to the voltage rising above a second threshold voltage. The clock distribution network increases the frequency of the clock signal provided to the processing unit in response to interruption of the droop detection signal.

The third circuitry may, upon the test of the condition having a positive result, evaluate a set of one or more parameters as specified by an entry in a second table corresponding with the entry in the first table. The fourth circuitry may initiate a power-management action based upon the evaluation of the set of one or more parameters.

Apparatuses and methods of distinguishing between a finger and stylus proximate to a touch surface are described.
