When, can monitor above-mentioned call information whether occurs on communication bus.To collect the call information on communication bus, the
The circuit for setting sample circuit related to other is often also needed on two memories.As previously described, when second memory judges
When inserting call information on communication bus, also judge whether itself has been labeled, if the two conditions are all met, lead to
Cross the second information that data wire sends second memory storage to imaging device.As elucidated before, if not needing second to deposit
Reservoir sends the second all information to imaging device, then first memory also needs to stop sending letter in second memory
Before breath, new call information is inserted to communication bus, continues to send the second information to notify second memory to stop.
, can also be only in the case where second memory be marked with to reduce energy consumption, second memory just starts monitoring
Whether above-mentioned call information is occurred on communication bus.And in the case that second memory above-mentioned two condition is all met, can be with
And then the clock cycle that call information occurs sends the second information；It is also contemplated that the response speed of second memory, first
Memory shifts to an earlier date N (N is more than or equal to 1), and the individual clock cycle inserts call information in communication bus, and second memory is N number of at this
It is just to start after the clock cycle to send the second information.
