Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail.
Fig. 1 provide a kind of service time register system embodiment calcspar, present embodiment is that be example the service time with memory computer system 1.Wherein, computer system 1 connection is in order to the display device 2 of display message.Computer system 1 comprises a mnemon 12, in order to a record and a computer system relevant variable 1 service time; And export/go into system 16 substantially and carry out the more operation of new variables jointly by the logic controller 10, the processing unit 14 and that are provided with timing unit 100, to reach the record computer system effect of 1 service time.In addition, computer system 1 comprises that also one leaves the supervisory routine 180 of storage element 18 in; Computer system 1 outputs to display device 2 by supervisory routine 180 1 service time with the computer system of calculating and shows.
In the present embodiment, the variable in the mnemon 12 can regularly be updated, in order to accumulative total computer system 1 service time of process.For new variables more regularly, the timing unit 100 that is arranged on logic controller 10 is when computer system 1 is in starting state, during circularly according to the length gauge of a schedule time, and periodically when the schedule time expires, give notice to processing unit 14, upgrade the variable that is recorded in mnemon 12 with notifier processes unit 14.
Logic controller 10 is a South Bridge chip or integral chip group for example, 100 of timing units can be in the South Bridge chip WatchDog Timer (Watchdog Timer) but an or program timer (programmable timer).With the WatchDog Timer is example, and it can be according to a schedule time timing that sets in advance in the registration shelves (registry) of logic controller 10.When the schedule time expires, WatchDog Timer promptly sends an interrupt notification, for example: system management interrupt (system managementinterrupt, SMI) to processing unit 14, make processing unit 14 store system state originally earlier, and enter System Management Mode (system management mode, SMM).After processing unit 14 enters System Management Mode, differentiate the classification of received system management interrupt earlier, again to basic output/go into to read in the system 16 corresponding Interrupt Service Routine (interrupt service routine, ISR), carry out special operation according to the instruction of Interrupt Service Routine.In the present embodiment, after processing unit 14 receives interrupt notification, promptly judge this interrupt notification earlier and sent, then exporting/going into the renewal routine 160 that reads correspondence in the system 16 substantially and carried out by timing unit 100.But if adopt the program timer timing, the driver of then can further arranging in pairs or groups again is to adapt to the operating system of different computers system 1, to carry out above-mentioned timing and advising process.
Upgrade routine 160 and be used for variable update that mnemon 12 is write down, make variable be directly proportional with the number of times that timing unit 100 timing expire.Wherein, processing unit 14 reads the variable that is write down in the mnemon 12 earlier according to the instruction of upgrading routine 160, variable is added certain value with new variables more again, and the variable after will upgrading once again writes back in the middle of the mnemon 12, becomes new record.
For example, begin to follow the trail of its service time post sales, before computer system 1 is dispatched from the factory, can be set to 0 with as initial value by manufacturer's end variable in mnemon 12 if want to dispatch from the factory in computer system 1.After selling, computer system 1 is activated beginning first, timing unit 100 promptly continues when each computer system 1 is starting state, during according to the length gauge of the schedule time, after the schedule time expires each time, processing unit 14 is promptly according to the instruction of upgrading routine 160, read variable from mnemon 12, variable is added definite value (for example at every turn adding 1), the variable that will be updated writes and replaces variable originally in the mnemon 12 again.Thus, the number of times that the variable in the mnemon 12 promptly can expire along with the schedule time and increasing progressively thus can be according to the up-to-date variable that is write down in the length of default time and the mnemon 12, and obtains the service time of computer system 1 accumulative total process.
Substantially, mnemon 12 is to utilize system management bus-bar (SMbus) or internal integration circuit (I2C) bus-bar to be connected in logic controller 10; When processing unit 14 is wanted data in the reading and writing mnemon 12, be by logic controller 10 and bus-bar and access/memory unit 12.
