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.

Information processing apparatus, information processing system, and information processing method

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

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.

Information processing apparatus for controlling transmission of information while varying transmission intervals

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.

Information processing apparatus

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.

An information processing apparatus includes a first central processing unit, a second central processing unit, and a returning unit. The first central processing unit has a normal operating state and a power-saving state in which power consumption is lower than in the normal operating state. The second central processing unit causes the first central processing unit to return to the normal operating state from the power-saving state. The returning unit causes the first central processing unit to return to the normal operating state in a case where the second central processing unit enters an anomalous state after the first central processing unit has entered the power-saving state.

Information processing apparatus and image forming apparatus

According to an aspect of the invention, an information processing apparatus includes a main board, an expanded CPU board connector, an external device connector, a detection unit. A first CPU is mounted on the main board. The expanded CPU board connector is disposed on the main board. An expanded CPU board is connectable to the expanded CPU board connector. A second CPU is mounted on the expanded CPU board. The external device connector is disposed on the main board. An external device is connected to the external device connector. The detection unit detects that the expanded CPU board is installed to the expanded CPU board connector. The first CPU controls the information processing apparatus to change a master of control of the information processing apparatus from the first CPU to the second CPU.
