How 20 bit address is generated in 8086

WebThe 8086 microprocessor is a16-bit, N-channel, HMOS microprocessor. Where the HMOS is used for "High-speed Metal Oxide Semiconductor". Intel 8086 is built on a single semiconductor chip and packaged in a 40-pin IC package. The type of package is DIP (Dual Inline Package). Intel 8086 uses 20 address lines and 16 data- lines. Web· Physical address formation: The 8086 addresses a segmented memory. The complete physical address which is 20-bits long is generated using segment and offset registers each of the size 16-bit.The content of a segment register also called as segment address, and content of an offset register also called as offset address.
