Abstract: Introduce a kind of dormancy of using- restore to the thronein theoperation way and improve the anti-interference ability method of theone-chip computer;Analyse its scope of application, provide and use thecircuit concretly; Combine the instance, analyse the characteristic of thehardware and software design under these kind of operation way.
Keyword: One-chip computer Restore to the throne /dormancyanti-interference Foreword
Introduction:
With the development at full speed of the microelectric technique, theperformance of the one-chip computer improves rapidly, demonstrate theoutstanding advantage in the operation, logic control, intelligent respect,replaced and enlarged the measuring that the circuit made up, control circuitby digital logical circuit, operation originally to a great extent, use veryextensivly. But because it have system halted, procedure run critical defectof flying etc, make it limit in a lot of important application of occasion.
A lot of technology in anti-interference , for example set up the softwaretrap, add thehardware to guard the gate in dog s circuit etc, can make thisproblem havebetter settlement, but still the existing problem: ① Guard thegate dog at the movement, mean and appear mistake already and run some time,this is not allowed in some occasions; ②Procedure appear circulation mistakevery much sometimes, but just guard the gate dog control link include and enter,adopt and guard the gate as to such a mistake dog unable to discern; ③ Inmeasure and control cycle among the long system, one-chip computer spend waitfor the peripheral hardware a large amount of time, will be interfered toowhen carry out and wait for the order. To these situations, we have tried themethod restored to the throne voluntarily in practice, alternate pulse ofadopting etc or restore to the throne waking according to external terms
