Von Neumann Vs Harvard Architecture

It uses the same physical memory address for instructions and data

• Von Neumann Architecture

• Harvard Architecture

Processors need two clock cycles to execute an instruction

• Von Neumann Architecture

• Harvard Architecture

It uses separate memory address for instructions and data

• Von Neumann Architecture

• Harvard Architecture

Simpler control unit design and development of one is cheaper and faster

• Von Neumann Architecture

• Harvard Architecture

Processor needs one cycle to complete an instruction

• Von Neumann Architecture

• Harvard Architecture

Control unit for two buses is more complicated which adds to the development cost

• Von Neumann Architecture

• Harvard Architecture

Data transfers and instruction fetches cannot be performed simultaneously

• Von Neumann Architecture

• Harvard Architecture

Used in personal computers, laptops and workstations

• Von Neumann Architecture

• Harvard Architecture

Data transfers and instruction fetches can be performed at the same time
