What is the internal architecture of 8086 microprocessor?
The internal architecture of Intel 8086 is divided into 2 units: The Bus Interface Unit (BIU), and The Execution Unit (EU).
How many segment registers does 8086 have?
four special
The 8086 has four special segment registers: cs, ds, es, and ss. These stand for Code Seg- ment, Data Segment, Extra Segment, and Stack Segment, respectively. These registers are all 16 bits wide.
How many segments are there in 8086?
➢ The 8086 architecture uses the concept of segmented memory. 8086 able to address a memory capacity of 1 megabyte and it is byte organized. This 1-megabyte memory is divided into 16 logical segments.
How many bytes is 8086 microprocessor?
Features of 8086 It has an instruction queue, which is capable of storing six instruction bytes from the memory resulting in faster processing. It was the first 16-bit processor having 16-bit ALU, 16-bit registers, internal data bus, and 16-bit external data bus resulting in faster processing.
What is the pin diagram and description of 8086 microprocessor?
Intel 8086 is a 16-bit HMOS microprocessor. It is available in 40 pin DIP chip. It uses a 5V DC supply for its operation. The 8086 uses 20-line address bus….Pin diagram of 8086 microprocessor.

What is the architecture and working of 8086 microprocessor?
So, lets now proceed further and understand the architecture and working of 8086 microprocessor. The architecture of 8086 microprocessor is composed of 2 major units, the BIU i.e., Bus Interface Unit and EU i.e., Execution Unit.
How many memory locations are there in 8086?
The 8086 has a 20 bit address bus, so it can address any one of 220, or 1,048,576 memory locations. 8086 CPU is divided into 2 independent functional parts to speed up the processing namely BIU (Bus interface unit) & EU (execution unit).
What type of bus does 8086 use?
Intel 8086 is a 16-bit HMOS microprocessor. It is available in 40 pin DIP chip. It uses a 5V DC supply for its operation. The 8086 uses 20-line address bus.
How many address lines are there in 8086 microcontroller?
Intel 8086 uses 20 address lines and 16 data- lines. It can directly address up to 2 20 = 1 Mbyte of memory. It consists of a powerful instruction set, which provides operation like division and multiplication very quickly.
