Information processor

Abstract: A multiple processor communications system including a control processor (12) and a scan processor (22) having its own program counter (40) enabling the efficient execution of subroutines. The scan processor (22) directly accesses a compiled user memory (15) which contains its operating program and also directly accesses the image memory (16) which contains the input and output data to perform the computations required by the program. The system includes error codes for distinguishing various error conditions including collision error conditions indicating illegal commands to the scan processor (22) when it is scanning and parity errors in the compiled user memory (15) and in the image memory (16).

Abstract: A novel personal electronic device includes a first (embedded) and second (non-embedded) processors including associated operating systems and functions. In one aspect, the first processor performs relatively limited functions, while the second processor performs relatively broader functions under control of the first processor. Often the second processor requires more power than the first processor and is selectively operated by the first processor to minimize overall power consumption. Protocols for functions to be performed by the second processor may be provided directly to the second processor and processed by the second processor. In another aspect, a display controller is designed to interface with both processors. In another aspect, the operating systems work with one another. In another aspect, the first processor employs a thermal control program. Advantages of the invention include a broad array of functions performed by a relatively small personal electronics device.

Abstract: Various embodiments are generally directed to techniques for assigning portions of a task among individual cores of one or more processor components of each processing device of a distributed processing system. An apparatus to assign processor component cores to perform task portions includes a processor component; an interface to couple the processor component to a network to receive data that indicates available cores of base and subsystem processor components of processing devices of a distributed processing system, the subsystem processor components made accessible on the network through the base processor components; and a core selection component for execution by the processor component to select cores from among the available cores to execute instances of task portion routines of a task based on a selected balance point between compute time and power consumption needed to execute the instances of the task portion routines. Other embodiments are described and claimed.

Abstract: PROBLEM TO BE SOLVED: To provide an information processor, an information processing method and a program, allowing a user to set a menu screen to be displayed on a display part of the information processor without taking trouble. SOLUTION: A cellphone A has: an input part 12; the display part 11; a display control part 14 making the menu screen having a plurality of items each corresponding to each of a plurality of functions be displayed on the display part 11; and a CPU 10 executing a function corresponding to the item indicated through the input part 12 of the plurality of items of the displayed menu screen. The cellphone A also has: a use frequency calculation part 15 calculating use frequency of each of the plurality of functions based on an execution situation of the CPU 10, and recording the calculated use frequency into a use frequency recording part 16 associatively with an identification number for identifying each of the plurality of functions; and a data output part 17 outputting the recorded identification number and use frequency as sort data for sorting the plurality of items of the menu screen.
