Architecture of 8086
The 8086 microprocessor architecture consists of a Bus Interface Unit and an Execution Unit. The Bus Interface Unit handles operations like instruction fetching, reading and writing memory operands, calculating memory addresses, address relocation, and interfacing with external devices. The Execution Unit contains the register set, a 16-bit ALU for arithmetic and logic operations, a flag register to reflect ALU results, and decoding and control units to decode instructions and generate signals to execute them.
30. 8086 microprocessor pipelined architecture
The 8086 microprocessor uses a pipelined architecture with two independent functional units: the Bus Interface Unit (BIU) and the Execution Unit (EU). The BIU handles data/address transfers between memory/I/O devices and the processor. The EU receives instructions from the queue, decodes them, and executes them. While the EU is decoding/executing an instruction, the BIU fetches the next instruction, allowing the two units to operate in parallel for improved performance over non-pipelined designs like the 8085. The 8086 can address registers as either 8-bit or 16-bit and uses segment registers to address 1MB of segmented memory space.

The 8086 architecture introduced Intel's first 16-bit microprocessor. It uses a 40-pin IC with an n-channel depletion mode silicon gate technology. The CPU logic is divided into an Execution Unit and Bus Interface Unit. The BIU interfaces with the external bus and executes bus operations, fetching instructions from memory and passing them to the EU. The EU then executes the instructions, manipulating registers and flags. The 8086 has 14 registers including data, segment, pointer, index, program counter, and flag registers.
Intel 8085 architecture
The Intel 8085 CPU architecture contains several functional blocks including registers, an ALU, instruction decoder, address buffers, and interrupt control. It has general purpose, temporary, and special purpose registers. The general purpose registers include the B, C, D, E, H, and L registers which can be combined to form 16-bit registers. It also has program and stack pointer registers. The ALU performs arithmetic and logical operations. The instruction decoder fetches and decodes opcodes to control other components like registers and address buffers. The CPU also has mechanisms for serial I/O, interrupts, and timing/control circuitry.

The 8086 microprocessor is a 16-bit CPU with a 20-bit address bus that can access up to 1MB of memory. It has two main units: the Bus Interface Unit (BIU) which handles memory access and addressing, and the Execution Unit (EU) which decodes and executes instructions. The BIU uses a 6-byte instruction queue to overlap instruction fetching and execution, improving performance. The 8086 supports segmented memory allowing code, data, stack and extra segments each up to 64KB in size.

The 8086 microprocessor is a 16-bit processor that can access up to 1 MB of memory. It has two main components - the Bus Interface Unit (BIU) handles bus operations like instruction fetching and memory access, while the Execution Unit (EU) decodes and executes instructions. The BIU contains registers for the code, data, extra, and stack segments as well as an instruction queue and pointer. The EU has registers for accumulation, base, count, data, indexing, and flags to indicate results. It decodes instructions from the queue and performs operations with its ALU and registers in a pipelined fashion.

Mpi chapter 2
The 8086 microprocessor is a 16-bit processor introduced by Intel in 1978. It has a 16-bit data bus and 20-bit address bus, allowing it to access up to 1MB of memory. The 8086 has an internal architecture divided into a Bus Interface Unit and an Execution Unit that can work simultaneously. The BIU handles external bus operations like fetching instructions and data from memory, while the EU decodes instructions and performs arithmetic/logical operations. The 8086 supports memory segmentation through the use of segment registers and pointers to generate 20-bit physical addresses.

- 2. Features • It is a 16-bit μp. • 8086 has a 20 bit address bus can access up to 220 memory locations (1 MB). • It can support up to 64K I/O ports. • It provides 14, 16 -bit registers. • Word size is 16 bits. • It has multiplexed address and data bus AD0- AD15 and A16 – A19.
- 3. It requires single phase clock with 33% duty cycle to provide internal timing. 8086 is designed to operate in two modes, Minimum and Maximum. It can prefetches up to 6 instruction bytes from memory and queues them in order to speed up instruction execution. It requires +5V power supply. A 40 pin dual in line package. Address ranges from 00000H to FFFFFH Memory is byte addressable - Every byte has a separate address.
- 4. Intel 8086/8088 Internal Architecture
- 5. Internal architecture of 8086 • 8086 has two blocks BIU and EU. • The BIU handles all transactions of data and addresses on the buses for EU. • The BIU performs all bus operations such as instruction fetching, reading and writing operands for memory and calculating the addresses of the memory operands. The instruction & 8088
- 6. • EU executes instructions from the instruction system byte queue. • Both units operate asynchronously to give the 8086 an overlapping instruction fetch and execution mechanism which is called as Pipelining. This results in efficient use of the system bus and system performance. • BIU contains Instruction queue, Segment registers, Instruction pointer, Address adder. • EU contains Control circuitry, Instruction decoder, ALU, Pointer and Index register, Flag register.
- 7. EXECUTION UNIT • Decodes instructions fetched by the BIU • Generate control signals, • Executes instructions. The main parts are: • Control Circuitry • Instruction decoder • ALU: The ALU performs the arithmetic, logic & shift operations required by an instruction.

- 10. Pointer And Index Registers • Used to keep offset addresses. • Used in various forms of memory addressing. • In the case of SP and BP the default reference to form a physical address is the Stack Segment (SS-will be discussed under the BIU) • The index registers (SI & DI) and the BX generally default to the Data segment register (DS). • The SI and the DI registers may also be used to access data stored in arrays
- 11. •SP: Stack pointer •Used with SS to access the stack segment BP: Base Pointer •Primarily used to access data on the stack •Can be used to access data in other segments •SI: Source Index register •is required for some string operations •When string operations are performed, the SI register points to memory locations in the data segment which is addressed by the DS register. Thus, SI is associated with the DS in string operations. •DI: Destination Index register •is also required for some string operations. •When string operations are performed, the DI register points to memory locations in the data segment which is addressed by the ES register. Thus, DI is associated with the ES in string operations.
- 12. FLAGS • 8086 has 16 bit flag register. • Contains 9 active flags. There are two types of flags in 8086 1.Conditional flags : 6 flags, set or reset by EU on the basis of results of some arithmetic operation. 2.Control flags : 3 flags, used to control certain operation of the processor.
