Harvard vs Von Neumann Architectures

There are two CPU architectures for the CPUs. Here briefly i'm trying to show the basic differences of those architectures  .
Controlling process unit is where input data get arithmetic calculation form the instruction code.
Data & instruction resides in same location at Von Neumann architecture means data and address bus have to use one path to transfer data.There is a la of communication because of that

But in Harvard it originally have two locations for data & instructions and that lag issue is not relevant to the this architecture.
