It depends what ARM you're talking about. The ARM7 uses the Van Neumann bus architecture (one bus for both data and instructions, and never both at the same time). The ARM9 uses a Harvard bus architecture (separate buses, one each for data and instructions).

I have not specifically examined ARM11, but as all earlier ARM architectures were Von Neumann I would expect for compatibility, it is also Von Neumann.

The previous answerer is incorrect. ARM9 and ARM11 are both Harvard.

Difference between von newman and Harvard computer architecture?

In a von Neumann architecture, program and data are stored in the same memory and managed by the same information-handling subsystem. In the Harvard architecture, program and data are stored and handled by different subsystems. This is the essential difference between the two architectures. In the original "Harvard computer", built in 1944 and for which the architecture is named, the program-handling task and the data-handling task were sufficiently different to result in two different storage technologies. Today, the vast majority of computers are von Neumann architecture because of the efficiencies gained in designing, implementing, and operating one memory system instead of two. However, in some niches, particularly certain embedded applications where the program is more-or-less hard wired, task requirements are such that the Harvard architecture can provide distinct operational advantages. Under certain conditions, a Harvard computer can be much faster than a von Neumann computer because data and program do not contend for the same information pathway, and storing the program in an immutable read-only memory can result in vast reliability improvements.
