rm PROD - this is a variant on the Von Neumann architecture, and I found alot of books with it, not just two - it describes the standard configuration of an x86/68k/etc machine
|concern = The topic is not notable. Searching Google Books for the terms "system bus model" and "von Neumann" (to prevent the return of irrelevant results discussing system bus models in the context of simulation) returns three results. Searching Google Scholar returns two. Of the three Google Books results, two are textbooks with trivial mentions of the topic, and the other is a mirror of this article. Of the two Google Scholar Results, one is the same textbook found in Google Books, and the other is what appears to be some university's internal teaching material.
