An information processing apparatus includes a first controller and a second controller. The first controller is configured to control an operation of the overall information processing apparatus. The second controller is configured to control an operation of a device. When detecting a trigger of resumption from a power saving mode, the second controller notifies the first controller of the detection of the trigger, and starts to initialize a function corresponding to the trigger.

Information processing apparatus

An information processing apparatus includes a first controller that performs control that does not depend on hardware; a second controller that is connected to the first controller through a communication path and performs control that depends on the hardware; and a memory in which first attribute information reflecting a first attribute of the first controller and second attribute information reflecting a second attribute of the second controller are stored. The first controller acquires a first control program for the first controller that is associated with a combination of the first attribute information and the second attribute information and performs control on a basis of the first control program, and the second controller acquires a second control program for the second controller that is associated with a combination of the first attribute information and the second attribute information and performs control on a basis of the second control program.

An information processing apparatus includes a first controller that operates while receiving first power and executes device-independent control; a second controller that operates while receiving second power and controls a device on a basis of a command from the first controller; a clock management unit that operates while receiving continuous power, and limits supply of a first clock signal to the first controller until the first power is supplied and limits supply of a second clock signal to the second controller until the second power is supplied; and a reset cancellation management unit that operates while receiving continuous power, limits supply of a first reset cancellation signal to the first controller until operation using the first clock signal starts and limits supply of a second reset cancellation signal to the second controller until operation using the second clock signal starts.

Information processing apparatus and circuit device

An electronic device includes plural modules; a return factor detection unit that detects a return factor causing return from an energy-saving state; and a return controller that causes the plural modules to start return processing upon detection of the return factor by the return factor detection unit. The plural modules include a first module and a second module that are connected by using a high-speed serial interface that needs preprocessing for establishment of connection without software, and the second module, which performs return processing upon receipt of a trigger of return from an energy-saving state through the first module, starts the preprocessing for establishment of connection using the high-speed serial interface in parallel with return processing of the first module.

Electronic device

A control system includes: a controller that controls a control unit of a control device, the control unit controlling multiple function units; and a restorer that is capable of receiving a first instruction for restoration from an energy-saving mode from a user who is in a proximate location near the controller, and a second instruction for the restoration from a user who is in a location further away than the proximate location, the restorer altering a timing for restoration of the control unit between a case where there the first instruction is received and a case where the second instruction is received.

Control system

An information processing apparatus includes a first controller and a second controller. The first controller performs processing dependent on hardware having a function. The second controller is connected to the first controller via a general-purpose communication path and performs processing not dependent on the hardware. Each of the first controller and the second controller transmits control information used for controlling the hardware to a counterpart controller of the first controller or the second controller via the communication path while varying a transmission interval in accordance with a type of the control information.

An information processing apparatus includes a first controller that performs a process dependent on hardware having a function, a second controller that performs a process independent of the hardware, and a power controller that, if there is a reason to resume supply of power to the second controller when supply of power to the first and second controllers has been restricted or stopped, activates both the first and second controllers or only the second controller depending on the reason.

Information processing apparatus for reducing power consumption by supplying power to a necessary controller of multiple controllers

An information processing apparatus includes a first controller and a second controller. The first controller performs processing dependent on hardware having a function. The second controller is connected to the first controller via a communication path and performs processing not dependent on the hardware. The second controller stores an execution command in a storage device. The execution command is for executing processing and has a format not dependent on the hardware. The first controller includes a converter, a memory controller, and an operation controller. The converter acquires the execution command from the storage device and converts the execution command into a command for controlling the hardware and dependent on the hardware. The memory controller writes the converted command into a memory. The operation controller reads the converted command from the memory and controls operation of the hardware.

An information processing apparatus includes first and second controllers. The first controller executes processing dependent on an individual piece of hardware having a function and stores information indicating an operating state of an individual piece of hardware. The information is different according to the piece of hardware. The second controller executes processing which is not dependent on any piece of hardware. When the information processing apparatus is powered ON, the first controller sends the information stored in the first controller to the second controller. The second controller controls a corresponding piece of hardware by using the information sent from the first controller.

A multiprocessor system including at least a first processor and a second processor, includes a storage unit that stores a first program executed by the first processor and a second program executed by the second processor, a memory unit that has a memory region used by the second processor, and a monitoring unit that is connected to the storage unit and the memory unit via a communication line, and, in a case where a program read from the storage unit is the second program, stores the read second program into the memory unit.
