Inter-processor communication was mentioned briefly in the context of distributed systems. Let’s take a look at some of the considerations that go into choosing a suitable inter-processor bus.
There are many considerations when choosing the communication medium used between processors. We will consider the following: timing, physical requirements, and development-team/project constraints.
In a real-time system, timing considerations are often some of the most important. If a message sent between nodes doesn’t make it to its destination on-time and intact, it can have serious consequences. The following is a list of items to consider in regard to timing when trying to choose the right communication medium:
