Types of CPUs Based on Architecture
Von Neumann Architecture
The Von Neumann Architecture is a fundamental concept in computer science and refers to the organization of the central processing unit (CPU) and memory in a computer system. It is named after the mathematician and computer scientist John von Neumann, who first proposed the concept in the 1940s.
The Von Neumann Architecture is characterized by a single memory bus that is shared by both the CPU and input/output devices. This means that data must be transferred between the CPU and memory in order to be processed. The Von Neumann Architecture also stores both program instructions and data in the same memory.
Examples of Von Neumann Architecture CPUs include the Intel 8086 and the Motorola 6809. These CPUs were widely used in personal computers during the 1980s and 1990s. The Von Neumann Architecture is still used in modern computers, although alternative architectures such as the RISC (Reduced Instruction Set Computing) architecture have been developed as well.
Harvard Architecture
The Harvard Architecture is a type of CPU architecture that is commonly used in computer systems. It is named after Harvard University, where it was first developed in the 1960s.
Explanation of Harvard Architecture
The Harvard Architecture is a type of CPU architecture that separates the memory and data processing units in a computer system. This means that the memory and data processing units are not connected to each other, but rather work independently.
Characteristics of Harvard Architecture
One of the main characteristics of the Harvard Architecture is that it has separate buses for data and instructions. This means that data and instructions are processed independently, and there is no overlap between the two.
Another characteristic of the Harvard Architecture is that it has a separate memory unit for data and instructions. This means that data and instructions are stored in separate memory units, and can be accessed independently.
Examples of Harvard Architecture CPUs
Examples of CPUs that use the Harvard Architecture include the Intel 8086, the Motorola 6809, and the Zilog Z8. These CPUs are commonly used in embedded systems, such as industrial control systems and consumer electronics.
