There is a processor, which loads and executes program instructions, and there is computer memory which holds both the instructions and the data. The harvard architecture has two separate memory spaces dedicated to program code and to data, respectively, two corresponding address buses, and. Harvard architecture has separate data and instruction busses, allowing transfers to be performed simultaneously on both busses. In this section, we will outline the important concepts and building blocks that. To perform a task, the computer is provided with program. The harvard architecture is a term for a computer system that contains two separate areas for commands or instructions and data.
