I've contended for some time that one of the key concepts missing from Computer Science education are the concepts associated with addressing. In fact, the first language that most new students are taught is Java, a language which goes out of its way to avoid programmers from using an address. So, I've wanted to write something that provides a rapid overview of addressing and I think I've found a readable way of explaining it; IBM's Power CAPI is special because it provides an I/O device to use the same addressing as is used in the typical program. How it does it and how addressing actually works is the purpose of this page called Power CAPI’s Secret is Addressing.
And, once again, on June 22, 2015, I have had the pleasure of having this article published on the web site The Platform. See Addressing Is The Secret Of Power8 CAPI
