Question

State the components of The Havard architecture​

Answer 1

The Harvard architecture is a computer architecture model that is used in many microcontrollers and microprocessors. The key components of the Harvard architecture are:

1. Instruction memory: A separate memory unit that stores the program instructions. This memory is usually read-only, meaning that the instructions cannot be modified during runtime.
2. Data memory: A separate memory unit that stores the data being processed by the program. This memory is usually read-write, meaning that the data can be both read from and written to during runtime.
3. Processor core: The central processing unit (CPU) that performs the arithmetic and logic operations. The processor core has direct access to both the instruction memory and the data memory.
4. Bus structure: A set of buses that connect the various components of the Harvard architecture. The instruction bus carries the instruction from the instruction memory to the processor core, while the data bus carries data between the data memory and the processor core.
5. Input/Output (I/O) interface: A mechanism for communicating with external devices, such as sensors and actuators. The I/O interface allows the processor core to read and write data from and to external devices.

These components work together to allow the Harvard architecture to efficiently execute the program instructions and perform data processing tasks. The separate instruction and data memory units allow the processor core to fetch and execute instructions while simultaneously accessing the data memory, improving performance and making the Harvard architecture well suited for real-time control applications.

Answer 2

Step-by-step explanation:

Harvard Architecture consists of Arithmetic Logic Unit, Data Memory, Input/output, Data Memory, Instruction Memory, and the Control Unit. Harvard Architecture has separate memory for data and instructions. In that way, both instruction and data can be fetched at the same time, thus making it comfortable for the users.
