Atmel's family say that 8051 controller follows the von-nuemann architecture. because register to register operation not possible in all 8051 family. if it is harvard means, it must support register to register transfer.Hence it concludes that 8051 followed by von-nuemann or Princeton architecture...
yes
In the Von Neumann (not "von humann") architecture instructions and data share the same bus and address space, while in the Harvard architecture instructions and data are accessed through separate buses.
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).
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.
