A method for managing shared passwords on a multi-user computer system is disclosed. A set of shared passwords and an administrator internal key are initially generated. After the receipt of an administrator external key, the administrator internal key is encrypted with the administrator external key. For each user level within the computer system, an internal key is generated by hashing the administrator internal key. For each user level within the computer system, each of the shared passwords encrypted with a respective one of the internal keys. The internal keys and the encrypted shared passwords are then stored in a non-volatile storage device.

Units are provided for determining whether or not a coordinate input is continued as being substantially the same coordinate and a predetermined time period has lapsed after an initial input of an arbitrary coordinate by a coordinate input unit. A first processing unit performs a first processing in accordance with the coordinate when the determination is not met, and a second processing unit performs a second processing different from the first processing when the determination is met.

Power usage of computing device components is controlled in a holistic manner. The projected total power consumption for the computing device to satisfy a power consumption policy for the device is determined. Power usage of each component of the computing device is controlled in a holistic manner—i.e., balancing the power usage of the component against the power usage of other components—so that the total power usage of the computing device falls within the projected total power consumption needed to satisfy the power consumption policy. How the user is currently utilizing the computing device may be periodically detected, based at least on a power consumption distribution of the components of the computing device. A current usage model is determined based on how the user is currently utilizing the computing device. The power usage of each component of the computing device is controlled based on the current usage model.

Devices, compilers and methods to reduce energy consumption associated with execution of a program by adjusting a computational capability of a CPU with higher accuracy than before. A device sets an appropriate computational capability to the CPU. It includes: changing a computational capability of the CPU every time each of a plurality of program areas included in the execution program is executed while the execution program is being executed, and measuring execution time each of the program areas; deciding an optimal computational capability required to execute the program area using the CPU, based on the execution time for each of the computational capabilities measured for the respective program areas; and performing setting of the optimal computational capability for executing the program area, which is to be used when executing the program area again in the course of executing the execution program, for each of the program areas.
摘要:
The method for controlling a computer that notifies an operating system of a request event corresponding to a device event from hardware. A device event may be generated, for example by a user operating a keyboard or mouse connected to the computer. That is, the device event occurs when a certain event is provided to the hardware of the computer. A request event causes a process corresponding to the device event to be performed under the control of an operating system. Then a response event from the operating system caused by the notification of the request event is accepted and a process event corresponding to the accepted response event is output to the hardware.
摘要:
An information processing system that can reduce the operating frequency of a CPU, or halt the operation of the CPU, at an adequate timing, even when the system is engaged in exchanging data with another independent apparatus (e.g., another PC) via a communication port (a serial port or a parallel port), or when a communication application is being executed. The system has (a) a CPU that operates in a normal mode, in a power saving mode in which less power is consumed than is required in a normal mode, or in a stop mode in which operation is completely halted; (b) at least one peripheral device; (c) a bus employed for communication between the CPU and the peripheral device; (d) a communication port, physically connected to another independent apparatus, for performing data transfer; (e) a bus cycle detector monitoring a bus cycle on the bus; (f) a state detector determining an operational mode of the CPU in response to a detection by the bus cycle of access of the communication port; (g) a signal generator providing, when the state detector ascertains that the operational mode is to be the power saving mode, a control signal to the CPU to set the CPU to the power saving mode; and (h) a CPU operation halting signal completely halting an operation of the CPU when the state determination means ascertains that the operational mode is to be the stop mode.
