Is ARM a Von Neumann or Harvard architecture?

Answer:

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).
