I asked "in a multiple processor system what is a 'state master'" and did not get an answer.
Erik Yes. And I simply assumed that you would have read this thread. If you do read the first post in the thread, you will notice (my emphasis added): The master processor runs a RS485 network to 6 slaves, and each slave returns its state on being polled.
The display is graphical, and has to respond to the slave states, the keypad, and the master state. Timing is getting tight. I was thinking of using a seperate processor to do the display only. The memory holding all the states is in the master. Now, you should know why I talked about a "state master" and a "display master". If the "state master" doesn't do any processing of the data, but needs to send all the state forward to the new processor that is responsible for the display, then almost all the complexity of the current master processor will move to the new processor, and the current master will just be a gateway. That would not result in any system improvement. |
