MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -8086 Microprocessor is an enhanced version of 8085Microprocessor that was designed by Intel in 1976. It is a 16-bit Microprocessor having 20 address lines and16 data lines that provides up to 1MB storage. It consists of powerful instruction set, which provides operations like multiplication and division easily.

Detailed explanation-2: -The 8086 has eight more or less general 16-bit registers (including the stack pointer but excluding the instruction pointer, flag register and segment registers). Four of them, AX, BX, CX, DX, can also be accessed as twice as many 8-bit registers (see figure) while the other four, SI, DI, BP, SP, are 16-bit only.

Detailed explanation-3: -Other notable 16-bit processors include the Intel 8086, the Intel 80286, the WDC 65C816, and the Zilog Z8000.

Detailed explanation-4: -The 8086 had eight (more or less general) 16-bit registers including the stack pointer, but excluding the instruction pointer, flag register and segment registers.

Detailed explanation-5: -Why is the Intel 8086 CPU called a 16-bit CPU? The registers and memory word size of the 8086 are 16 bit-meaning it can operate on 16 bit values and address 65536 bytes of memory at a time.
