1 Introduction to 8086 Microprocessor

•The Intel 8086 is a 16-bit microprocessor.

•It is used as the CPU in a microcomputer.

•The term 16-bit means that its ALU, internal registers, and most of its instructions are designed to work 16-bit binary words.

•It has 16-bit data bus and 20-bit address bus.

•Words will be stored in two consecutive memory locations.

•If the first byte of a word is at an even address, the 8086 can read the entire word in one operation.

•If the first byte of the word is at an odd address, the 8086 will read the first byte in one operation, and the second byte in another operation.
