Study Notes
- Von Neumann's architecture, also known as stored memory architecture, keeps data and instructions in the same main memory.
- Stored memory refers to the data and program being stored in memory. Data is constants and variables, while instructions are sets of commands for processing work.
- Main memory is where both data and instructions are stored. Instructions can be stored in some addresses, while data can be stored in others.
- The architecture is opposite to Harvard architecture, which stores instructions in different memory and data in different memory.
- Von Neumann's architecture includes the central processing unit (CPU), which contains the arithmetic and logical unit (ALU) and registers.
- ALU consists of various circuits, such as adders, subtractors, and shift operations, which perform arithmetic and logical operations.
- Registers are the fastest memory available, storing temporary data and intermediate results. They come in various sizes and help reduce the burden on the main memory by storing data temporarily and intermediately.
- The control unit generates timing signals and control signals, which determine the sequence of instructions to be executed and control access to registers and main memory.
- The input-output system includes peripheral devices like keyboards, monitors, and other output devices, which are connected through various buses and help input and output data to and from the main memory and CPU.
- The storage and processing of data involve calling it from the main memory to the CPU, processing it in the registers and ALU, and returning the output to the main memory for further use or storage.
