Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, and reference
The embodiment of the present invention is further described in attached drawing.
Based on above-mentioned purpose, the first aspect of the embodiment of the present invention proposes the one of a kind of memory system control method
A embodiment.Shown in fig. 1 is the schematic flow chart of this method.
As shown in fig. 1, which may comprise steps of:
Step S101, after system electrification, progress hardware initialization and load store and management program first；
Step S102, determines main control unit and from control unit, for example, can be judged automatically by hardware circuit it is main,
From control unit；
Step S103 after the completion of initialization, is counted if what is detected is main control unit using main control unit
According to access and data management, while to from control unit send shared information and with from control unit carry out real-time heart beat friendship
Mutually；
Step S104, if what is detected is to pass through number using from control unit after the completion of control unit, initialization
The shared information of main control unit transmission is received according to network and shared information is stored in local, while being carried out with main control unit
Heartbeat interaction；And
Step S105 is interrupted in response to heartbeat interaction and is deposited using data are continued according to shared information from control unit
It takes and data management.
Existing dual control storage scheme can not be applied directly on domestic processor platform, even if state can be transplanted to
It produces on processor platform, it is also desirable to it does largely transplanting and is adapted to work, this not only adds research and development costs, and the period is long,
It is unable to satisfy current urgent application demand.Application of the present invention in view of domestic processor own characteristic and data-storage system
Demand proposes the above-mentioned memory system control method based on domestic processor platform, realizes based on domestic processor platform
Storage system Redundant Control, effectively improve data storage reliability.
In a preferred embodiment, heartbeat interaction may include: periodically to be sent out from control unit to main control unit
Send heartbeat packet；Heartbeat packet is received with main control unit and in the given time to the response sent from control unit for heartbeat packet
Signal.
In a preferred embodiment, if it may include: from control unit twice in succession predetermined that heartbeat interaction, which is interrupted,
