The 8086 microprocessor is a 16-bit microprocessor developed by Intel and released in 1978. It was the first x86 microprocessor and the first in a long line of Intel processors based on the x86 architecture. The 8086 was used in many early personal computers, such as the IBM PC and the Apple Macintosh.
The 8086 has a 20-bit address bus and can address up to 1 megabyte of memory. It also has a 16-bit data bus and can perform 16-bit operations. It has a clock speed of 5 MHz and was later improved to 10 MHz with the release of the 8086-2.
The 8086 uses a complex instruction set computer (CISC) architecture, which means it has a large number of instructions that can perform a wide variety of tasks. This makes programming in assembly language for the 8086 more complex than for a reduced instruction set computer (RISC) architecture.
The 8086 also introduced the concept of segments and offsets to extend the size of the address space. Segments are used to divide memory into different sections, and offsets are used to access specific locations within a segment.
The 8086 microprocessor was widely used in personal computers, industrial control systems, and military applications. Its popularity led to the development of the 80286, 80386, and 80486 processors, which were compatible with the 8086 and added more features and capabilities.
Today, the 8086 microprocessor is considered to be a classic and its architecture is still taught in computer science and electrical engineering courses as a way to understand the evolution of computer architecture.
