Embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched The specific embodiment stated is used only for explaining the present invention, rather than limitation of the invention.It also should be noted that in order to just It illustrate only part related to the present invention rather than entire infrastructure in description, attached drawing.
Fig. 1 is the flow chart of the multitask monitoring and managing method in SPI-NAND provided in an embodiment of the present invention, and this method can be with Performed, specifically comprised the following steps by the control chip of SPI-NAND：
Step 101, the definite one or more tasks that will start in pending task queue；
Fig. 2 is the multitask schematic diagram in SPI-NAND provided in an embodiment of the present invention, and processor handles work queue, and Each work in work queue corresponds to the task of SPI-NAND again, and the type of these tasks includes erasing (Erase), write-in (Program), read (Read) and reset (Reset), SPI-NAND can carry out multiple tasks process in the same time, control Chip supervises task process, and first having determined which task is i.e. will be to be started, these tasks can according to actual conditions To be one or multiple, when there is multiple tasks to start, the type of this multiple tasks can include above-mentioned four kinds Any of type is a variety of, i.e., starting at the same time for task can be same type of task or different types of Task.
Step 102, according to the type of pre-set timeouts correspondence and one or more task determine timing The duration of device, the timeouts correspondence are used for the correspondence for representing task type and task duration；
Timeouts correspondence is set in advance, its method to set up includes：Obtain the SPI- of each producer The task type of NAND and the maximum duration for performing each generic task consumption；For each task type, the task type pair is recorded The maximum consumption duration answered, and the corresponding task of the task type is obtained according to maximum consumption duration and default redundancy duration calculation Duration, the maximum consumption duration be each producer perform the generic task consumption maximum duration in the maximum；According to each The respective task duration of service type obtains timeouts correspondence.First determine the firmware whole factories to be supported of SPI-NAND Family, obtains each producer and performs the maximum that each generic task (including wipe, write, read and reset) of SPI-NAND consumes respectively Duration, the maximum each producer in each task type performed in the maximum duration of generic task consumption are determined as the task class The corresponding maximum consumption duration of type, for example, erasure task, the SPI-NAND for having 3 producers respectively is consumed when performing the task Maximum duration, wherein the maximum is determined as to the maximum consumption duration of erasure task.This is consolidating for compatible SPI-NAND The part whole producers to be supported.Then on the basis of the maximum consumption duration of each task type, plus redundancy duration, the duration It is one times of maximum consumption duration to be typically set at, for example, the maximum consumption duration of erasure task is determined as 1s, then it is corresponded to Redundancy duration be also 1s, the task duration of the erasure task finally obtained is 2s.This is in order at the firmware operation of SPI-NAND Stability and reliability consideration.Finally obtain time-out according to all task types and the corresponding task duration of task type and set Determine correspondence.
One or more respective task durations of task that will start can be obtained based on timeouts correspondence, be Compatible each task, by the wherein time longest duration for being determined as timer, this represent if control chip at one or Task duration maximum if more than does not receive completion status feedback also in multiple tasks, then must be in tasks carrying It there is a problem, cause to complete within its reasonable time, control chip performs in order not to influence follow-up work at this time, can only The forced interruption task.
Step 103, start timer while one or more task starts, which is used to reach fixed in timing When device duration when send overtime feedback；
Start timer while one or more task starts, the duration of timer be exactly obtained in step 102 when Between longest task duration, once timer timing, which reaches the longest task duration, will send overtime feedback.
Step 104, receive time-out feedback before, monitor whether that the completion status for receiving one or more tasks is anti- Feedback；
Control chip can monitor whether to receive one or more tasks always before the time-out feedback of timer is received Completion status feeds back (ready), if receiving completion status feedback, it is determined that completion status feeds back corresponding task and completes and tie Monitoring of the beam to the task.
Step 105, when receive time-out feedback when, for do not receive completion status feedback task carry out forced interruption.
Control chip goes out to interrupt monitoring mechanism using spill-over, when receiving the time-out feedback of timer, into interrupt processing Function, forced interruption do not receive the task of completion status feedback.Control chip can be sent out error feedback (Error Response) so that the firmware of SPI-NAND can determine and mark to the block of operation exception.
The technical solution of the present embodiment, is timed the setting of device by the multitask to executory SPI-NAND, and one Denier time-out also confiscates the completion status of task feedback, will the forced interruption task, can accurately and timely found the abnormal situation, The efficiency of abnormality processing is improved, saves processing time.
Based on the above technical solutions, Fig. 3 is the multitask supervision in SPI-NAND provided in an embodiment of the present invention The flow chart of method, timeouts correspondence is set according to above method control chip, determines will start one or more A task, and determine the duration of timer, start timer while one or more task starts, monitor whether to receive Completion status to one or more tasks is fed back, if receiving completion status feedback, it is determined that completion status feedback corresponds to Task complete and terminate the monitoring to the task, when receive time-out feedback when, for do not receive completion status feedback Task carries out forced interruption.
Fig. 4 is the structure diagram of the multitask maintenance device in SPI-NAND provided in an embodiment of the present invention, with reference to figure 4, which includes：Task module 11, starting module 12, monitoring modular 13 and interrupt module 14, wherein, task module 11, is used In the one or more tasks for determining to start in pending task queue；Corresponded to according to pre-set timeouts The type of relation and one or more of tasks determines the duration of timer, and the timeouts correspondence is used to represent to appoint The correspondence of service type and task duration；Starting module 12, for starting while one or more of task starts The timer, the timer are used to send overtime feedback when timing reaches the duration of the timer；Monitoring modular 13, For before the time-out feedback is received, monitoring whether to receive the completion status feedback of one or more of tasks；In Disconnected module 14, for when receiving the time-out feedback, being forced for not the receiving the completion status feedback of the task Interrupt.
Based on the above technical solutions, the monitoring modular 13, is additionally operable to before the time-out feedback is received, if Receive the completion status feedback, it is determined that the completion status feeds back corresponding task and completes and terminate to the task Monitoring.
