Harvard Architecture | Computer Science

Harvard Architecture is one of the two most commonly used and well-known architectures in computer architecture. Harvard architecture has two separate storage paths for instructions and data.

1. HARVARD Architecture

2. Definition of Harvard Architecture A computer architecture in which instructions or program code and data are stored at two different memory locations with each of them having different bus systems is called Harvard architecture

3. How is it different form Von-Neumann architecture? Harvard architecture is a computer architecture with two separate memory locations for program and data but program code is not accessible to be read as if it is data Von-Neumann architecture has only one bus through which both program and data has to be passed and are required to be scheduled when they should pass through that bus system and there is only one memory location for both of them.

4. Harvard mark I The IBM Automatic Sequence Controlled Calculator (ASCC), called Mark I by Harvard University’s staff, was a general purpose electromechanical computer The first program to run on in this computer was initiated by john Von-Neumann in march, 1944.

5. Advantages and disadvantages Advantages : Since there are two different buses, there is no need of scheduling the instructions and data like in Von-Neumann architecture Harvard architecture allows a simultaneous access to both the code as well as data Disadvantages : This architecture is not widely used but modified (variation of Harvard architecture) Harvard architecture is Complexity in architecture
