Abstract
Abstract An information processing apparatus backs up status of a CPU (10) and content of a main memory (30) into a back-up memory (50) at the time of power-off, restores the data backed up in the back-up memory at the time of power-on to resume data processing, and informs the start of the resumed data processing or the termination of the data processing by a buzzer. <IMAGE> <IMAGE>

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
75 words
An information processing apparatus comprising: memory means connected to control means through a bus line; status back-up means for backing up the status of said control means and the content of said memory means at the time of power-off; status restore means for restoring the status backed up in said status back-up means at the time of power-on to resume the data processing; and inform means for informing the termination of the data restoring processing.
Claim 2
Dependent Claim
145 words
A data back-up/restore system of an information processing apparatus comprising memory means connected to control means through a bus line; status back-up means for backing up the status of said control means and the content of said memory means at the time of power-off; and status restore means for restoring the status backed up by said status back-up means at the time of power-on to resume the data processing; said system comprising the steps of: backing up (first environmental status) configuration at the time of power-off by said status back-up means; comparing the first environmental status configuration at the time of power-off backed up by said status back-up means with a second environmental status configuration when the power in turned on; and permitting the use of the apparatus by a user when the first environmental status configuration is identical to the second environmental status configuration.
Claim 3
Dependent Claim
34 words
A data back-up/restore system of the information processing apparatus according to Claim 2, wherein the first environmental status configuration is error detection processing information for the data backed up by said status back-up means.
Claim 4
Dependent Claim
24 words
A data back-up/restore system of the information processing apparatus according to Claim 2 wherein the first environmental status configuration is device connection status information.
Claim 5
Dependent Claim
24 words
A data back-up/restore system of the information processing apparatus according to Claim 2 wherein the first environmental status configuration includes I/O port status information.
Claim 6
Dependent Claim
48 words
A data back-up/restor system of the information processing apparatus according to Claim 2 wherein a processing speed of said control means from the back-up by said status back-up means to the restore by said status restore means is changed to a high speed irrespectively of a current speed.
