Arithmetic apparatus with resume function

摘要

An arithmetic apparatus (110) for enabling a program (160) to be activated with a shorter startup time afterthe arithmetic apparatus (110) restarts. Data relating to the current state of a predetermined application program (160) is temporarily stored in a volatile main storage device (103) (e.g. RAM). A data saving means saves the current state data to a nonvolatile storage device (106) (e.g. flash memory) while an executing means (101) (e.g. CPU) is still executing the application program (160) under the control of a operating system (161). This data is stored even when the power to the arithmetic apparatus (110) is disconnected. After the arithmetic apparatus (110) restarts and before the application program (160) is executed by the executing means (101), a transmitting means transmits the previously saved data from the nonvolatile storage device (106) to the main storage device (103). A producing means then produces a previous state on the basis of the previously saved data allowing the executing means (101) to execute the application program (160) in the produced previous state.
