Unit IX: Overview of Intel 8086 | BCA 3rd Semester Microprocessors Notes Pdf

The Intel 8086 microprocessor architecture is designed for two modes namely the minimum mode and the maximum mode. When only one 8086 CPU is to be used in a microcomputer system the 8086 is used in the minimum mode. In this mode, the CPU issues the control signals required by memory and input/output device. In a multiprocessor system, it operates in maximum mode, in this mode, the control signals are generated with the help of an external bus controller (8088).
