1. A coordinated operation method, comprising:

  • (a) providing a cellular phone including two processors in an interior of the cellular phone, the processors further includinga host processor which performs processing related to communication with an exterior of the cellular phone, andan engine processor which is dedicated to screen display processing and audio data output processing of a work and which executes the work under management of said host processor,wherein the processors operate in a coordinated manner;

    (b) an acquisition process in which said host processor acquires a main body portion of said work and also acquires work management information related to a utilization limit, including an execution limit for said work;

    (c) a work load process in which said host processor loads said main body portion of said work into said engine processor;

    (d) a work execution decision process in which, in response to a work execution command from a user, said host processor refers to said work management information, and decides whether or not said work can be executed;

    a work execution command transmission process in which, if the result of the decision in said work execution decision process is affirmative, said host processor sends an execution command for said work to said engine processor;

    the engine processor outputting an engine display image signal (BID) as a display image signal (MID) if a signal level of a host output control signal (HCT) of the execution command is below a predetermined level, and a signal level of an engine output control signal (ECT) is above the predetermined level;

    the host processor outputting the host display image signal (HID) as the display image signal (MID) if the signal level of the host output control signal (HCT) is below the predetermined level, and the signal level of the engine output control signal (ECT) is also below the predetermined level; and

    executing said work.
