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.

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.

According to an aspect of the invention, there is provided a data transfer control device that carries out data transfer in a data transfer system, in which plural bus masters are connected to a system bus and the data transfer between the bus masters is arbitrated by bus arbitration of each of the bus masters, between the bus masters, the data transfer control device including: an execution cycle monitoring section that monitors an access state for the system bus at the bus master when plural bus masters simultaneously request a use right with respect to the system bus; and a function execution order changing control section that changes an execution order of plural functions included in the bus master to be monitored, based on the access state monitored by the execution cycle monitoring section.

An image processing apparatus has a buffer storage section for temporarily storing image data supplied from a system bus; an image processing section for receiving the data read out of the buffer storage section for performing image processing on the received data; a storage section for temporarily storing output data of the image processing section and transferring the output data to the system bus; a gate section for releasing connection between the system bus and the buffer storage section; and a control section for controlling the respective sections so that input/output of data with respect to the image processing section and input/output of data with respect to the system bus are performed in parallel. Accordingly, the transfer on the bus, and the internal transfer from the buffer to the image processing apparatus are operated separately for each other, so that the image processing apparatus can be operated at a high speed.
