Abstract: A method for performing a quick boot and a general boot at a basic input output system (BIOS) stage is described. A computer is powered on. An embedded controller firmware or a BIOS determines whether a quick boot key is pressed. If the quick boot key is not pressed, a boot flag is changed from Quick Boot to General Boot. If the quick boot key is pressed, the BIOS determines whether the boot flag is set to Quick Boot. If it is determined that the boot flag is set to Quick Boot, an initialization of drivers preset by the quick boot is performed, and uninitialized drivers are initialized at a stage when an operating system is started. If it is determined that the boot flag is set to General Boot, an initialization of all drivers is performed.

The plurality of storage devices are bus-connected to one clock signal line and one data signal line connected to the controller. Each of the plurality of storage devices stores identification information in advance to distinguish the storage devices from each other.

A frequency of a clock signal during the identification information transmission period is set to be lower than a frequency of the clock signal during the data transmission period.

Abstract: Implementations of the present invention may involve methods and systems to improve the combined power consumption and thermal response of individual components of a computer system as the components are stressed concurrently during simulation or testing of the system. A group of operating system-level instruction sets for several individual components of the computer system may be designed to stress the components and executed concurrently while power and thermal measurements are taken. The instruction sets may utilize one or more software threads of the computer system or hardware threads such that minimal interference between components occurs as the system is tested. Further, the system components may be partitioned between separate instruction sets. By minimizing the interference between the components while the system is operating, a more accurate power consumption and thermal effect measurements may be taken on the computer system to better approximate the performance of the system.

Abstract: A method and system for power source management of a portable device. A power source used to supply electrical energy for a portable device should ideally operate with a constant terminal voltage. However, the terminal voltage of a cell or group of cells used as a source of electrical energy can be expected to reduce in amplitude over its operational lifetime. Near the end of operational lifetime, the terminal voltage of such a source can be expected to decrease rapidly. Furthermore, the source terminal voltage will also exhibit significant variations in amplitude in response to changes in electric current demands on the source. Such source voltage variations can impair or even prevent proper operation of the electronic circuits within the portable device. Power management for proper operation of a portable device is necessary to ensure proper device operation and to prevent loss of data.

Abstract: A mechanism is provided for scheduling application tasks. A scheduler receives a task that identifies a desired frequency and a desired maximum number of competing hardware threads. The scheduler determines whether a user preference designates either maximization of performance or minimization of energy consumption. Responsive to the user preference designating the performance, the scheduler determines whether there is an idle processor core in a plurality of processor cores available. Responsive to no idle processor being available, the scheduler identifies a subset of processor cores having a smallest load coefficient. From the subset of processor cores, the scheduler determines whether there is at least one processor core that matches desired parameters of the task. Responsive to at least one processor core matching the desired parameters of the task, the scheduler assigns the task to one of the at least one processor core that matches the desired parameters.

Abstract: A central processing unit (CPU) can specify an initial (e.g., baseline) frequency for a clock signal used by a device to perform a task. The CPU is then placed in a reduced power mode. The device performs the task after the CPU is placed in the reduced power mode until a triggering event causes the device to send an interrupt to the CPU. In response to the interrupt, the CPU awakens to dynamically adjust the clock frequency. If the clock frequency is reset to the baseline value, then the CPU is again placed in the reduced power mode.
