Abstract

The present invention relates to a digital computer system and a method of using the same, which can be easily switched to a working environment, comprising: a central processing unit which is a central element of a digital computer system; A bus which interconnects the various elements constituting the central processing unit and the system to transfer information between the elements; First memory means coupled to the bus to provide a place for the CPU to load system software and user software; Second memory means connected to the bus and in which a specific program to be executed by the CPU is already loaded; Backup memory means connected to the bus and storing contents of the first memory means and state information of system hardware to store a work environment of a user; It is connected to the bus and the power is turned off by the user or the power supplied from the outside is cut off the power supply control means for maintaining the power until the current working environment is stored in the backup memory means, providing a different environment It takes a short time to run an application on a digital computer system that can work under each environment, and even if the task is interrupted, it can restore the contents already saved and continue again, and it is possible to quickly switch between different working environments. Has the effect.

Claims (10)

A central processing unit which is a central element of the digital computer system; A bus which interconnects the various elements constituting the central processing unit and the system to transfer information between the elements; First memory means coupled to the bus to provide a place for the CPU to load system software and user software; Second memory means connected to the bus and in which a specific program to be executed by the CPU is already loaded; Backup memory means connected to the bus and storing contents of the first memory means and state information of system hardware to store a work environment of a user; And a power control means connected to the bus to maintain power until the current work environment is stored in the backup memory means even when the user turns off the power or the power supplied from the outside is cut off. Digital computer system that is easy to change environment. The method of claim 1, wherein the backup memory means is composed of at least one or more memory blocks connected to the bus, the one memory block is a digital easy to change the work environment, characterized in that for storing one work environment Computer system. 3. The digital computer system as claimed in claim 2, wherein the backup memory means comprises a RAM capable of reading and writing so that the CPU can store a specific working environment via a bus. The digital computer system as claimed in claim 2, wherein the backup memory means is configured to only read a work environment in which the central processing unit is already stored. In the process of performing a specific task in a digital computer system controlled by the central processing unit by connecting the power control means and the backup memory means to the bus, the user interface hardware is initialized after the power is applied to perform the task to be performed by the user. Selecting a memory block in the stored backup memory means; Setting a system state according to a selected working environment by information stored in the selected memory block; Transferring a system control right to a selected job from the control program controlling the process, and performing the work; A method of using a digital computer system that can be easily switched to a work environment, characterized in that when the power is turned off for work interruption, the work environment being executed by the power control means is stored in a memory block in the backup memory means. The work environment according to claim 5, wherein the memory block in the backup memory means consists of a read-only ROM so that when the user turns off the power, the external power supply is cut off without storing the work environment in which the power control means is executing. How to use a switchable digital computer system. 6. The method of claim 5, wherein the power off for interrupting work is automatically powered off when the system is not in use for a certain period of time. The method of claim 5, wherein the power-off for interrupting the work is switched to the work environment characterized in that the backup auxiliary power supply is operated by the power supply control means when the external power supply to the system itself is turned off. Easy to use digital computer system. In a process of switching from a digital computer system to another working environment, the step of executing an application program under a specific working environment by a user; Requesting the user to stop the work being performed and to perform work in another environment; Storing the working environment in a corresponding memory block in the backup memory means; The system state is set according to the requested working environment by the information stored in the requested memory block; A method of using a digital computer system that can be easily switched to a work environment, characterized in that the system control rights are transferred to the requested work from the control program that has performed the process. 10. The method according to claim 9, wherein the memory block in the backup memory means consists of a read-only ROM so that the working environment is not stored in the backup memory means. ※ Note: The disclosure is based on the initial application.
