This is a machine architecture, according to the diagram, and according to various books. It needs to be rewritten, to distinguish that this is not a CPU architecture. (hence the CPU is a unit in this model, not the entirety of the model). I/O devices, main memory and the CPU all exist on a system bus to communicate with one another, the system bus is composed of data lines, address lines and control lines. That is the standard way that PCs are built on when the system bus was a local bus (ie. the original IBM PC, when simplified to a basic diagram)
So what the article describes is wrong, thus efforts to find references supporting its notability are also flawed since the search terms used do not accurately summarise the topic's essentials? Rilak (talk) 04:44, 20 October 2010 (UTC)[reply]
I left a note about it at Wikipedia_talk:WikiProject_Computing, and someone has already said that deletion is not uncontroversial. What the article describes is a model where the CPU is a concept that exists, whereas in the original VNA, the concept of the CPU does not exist, since the VNA predates the CPU. This article is about a computer architecture, that includes the concept of a CPU, and is in many different books, called derivative of the Von Neumann architecture, and in other books, is classified as a Von Neumann architecture. The description, as sparse as it is, is meaningfully accurate except for its statement about combining the ALU with the CPU, which is wrong. It combines the ALU and the CU (control unit). 76.66.200.95 (talk) 10:51, 20 October 2010 (UTC)[reply]
