On the other hand, Fig. 6 shows a kind of microcontroller 1000, interrupt request distribution device 100 is integrated into the microcontroller 1000
In, and Fig. 8 shows another microcontroller 2000 to this, electronic functional elements are integrated into the microcontroller 2000.
Fig. 9 schematically shows a kind of embodiment of the operation method according to the present invention for electronic functional elements 500
Simplified flowchart.Input signal i is received in step 600（Fig. 5）, in step 610（Fig. 9）In thus produce it is at least one in
Disconnected request signal irq（Fig. 5）, postpone interrupt request singal irq in step 620, and in act 630 in output delay
Disconnected request signal irq_o.
Can be advantageously with arbitrary as in for example occurring in microcontroller technical field according to the principle of the present invention
Disconnected source and/or interruption Su Zuhe.By time delay it is suitable it is previously given can advantageously compensate reached interruption please
The just corresponding interrupt requests of high time rate or time colonel asked, this is the application based on interrupt requests of operation（Task）Carry
For more free spaces.Make full use of system according to the principles of the present invention can preferably internally the time it is upper balanced and
It is derived from the stability improved.Especially it can be prevented from, multiple times, upper simultaneous interrupt requests were mutually blocked.
It can also be used particularly advantageously in following system according to the principle of the present invention, interrupt requests are used in the system
Make direct memory access（Direct memory access, direct memory access (DMA), referred to as " DMA "）Trigger（Start
Signal）.In some communication modules（Such as SPI, MSC）In, communication can be with continuous time frame（Such as per 10ms）Operation is outer
The bus user in portion（Such as slave）.Here, communication or data transfer task by computing unit such as 10ms time frame
Beginning be set to buffer（English：Queue, queue）In.All tasks must be transmitted within 10ms, because queue
Refilled in next 10ms frames.Task advantageously by（Such as type " being transmitted ", " new task starts " etc.）In
Disconnected request（Interrupt）Finished increasingly by computing unit.Therefore it is likely to occur at the beginning of 10ms frames for system very high
Interrupt load because transmission it is almost back-to-back（Bursts）Carry out.Because the generally endless full packing from the time of 10ms frames,
Relatively long rest is formed after the transmission until the next 10ms cycles start.At beginning, high fully loaded causes, other operations
Task can not terminate in time.High task shake is talked about herein, and the high task shake makes whole system unstable.These
Shortcoming can be avoided by using the principle according to the present invention, and its mode is, such as the beginning of the time frame in 10ms is tired out
The interrupt requests that product occurs are corrected and therefore at this in time by appropriately selected different time delay T1, T2, T3
More uniformly it is distributed on time frame.
