Which type of architecture uses different storage space for program code and the data?(a) Von Neumann architecture(b) Harvard architecture(c) Fragmented architecture(d) Split cell architectureThis question was addressed to me in an international level competition.The origin of the question is Digital Signal Processing topic in section Digital Communication Techniques of Avionics

Answer»

The CORRECT choice is (b) Harvard architecture

The explanation is: In a Harvard architecture MICROPROCESSOR, there are TWO memories, a PROGRAM or instruction memory, usually a ROM, and a data memory, which is a RAM. Also, there are two data paths into and out of the CPU between the memories. Because both instructions and data can be accessed simultaneously, very high-speed operation is possible.
