Explain 8086 system architecture
The 8086 (also called iAPX 86) is a 16-bit microprocessor chip designed by Intel between early 1976 and June 8, 1978, when it was released. The Intel 8088, released July 1, 1979, is a slightly modified chip with an external 8-bit data bus (allowing the use of cheaper and fewer supporting ICs), and is notable as the processor used in the original IBM PC design. WebFeb 24, 2024 · As they improve the architecture, they kept 86 at the end of the model number, the 8086. This line of processors was then known as the x86 architecture. On the other hand, x64 is the architecture name for the extension to the x86 instruction set that enables 64-bit code. When it was initially developed, it was named as x86-64.
