von-Neumann Architecture

18A microcontroller with a von-Neumann architecture has one memory block and a data bus of 8-bits in length. This data bus serves as the point through which all data passes. The limitations of this architecture include the inefficiency of the data bus design, which sometimes becomes overloaded and causes the rate of communication within the microcontroller to slow considerably.
