    VON NEUMANN ARCHITECTURE It is an ancient computer architecture based on the stored program computer concept. The same physical memory address is used for instructions and data. There is a common bus for data and instruction transfer. Two clock cycles are required to execute a single instruction. ItRead more

    VON NEUMANN ARCHITECTURE

    • It is an ancient computer architecture based on the stored program computer concept.
    • The same physical memory address is used for instructions and data.
    • There is a common bus for data and instruction transfer.
    • Two clock cycles are required to execute a single instruction.
    • It is cheaper.
    • CPU can not access instructions and read/write at the same time.
    • It is used in personal computers and small computers.

    HARVARD ARCHITECTURE

    • It is a modern computer architecture based on Harvard Mark I relay-based model.
    • A separate physical memory address is used for instructions and data.
    • Separate buses are used for transferring data and instruction.
    • An instruction is executed in a single cycle.
    • It is more costly than Von Neumann’s Architecture.
    • CPU can access instructions and read/write at the same time.
    • It is used in microcontrollers and signal processing.
