microprocessor-architecture of 8086

**Microprocessor Architecture of 8086 (100 words):** The 8086 microprocessor is a 16-bit processor with a 20-bit address bus, allowing it to address up to 1 MB of memory. It has a **complex architecture** with the following key components: 1. **ALU (Arithmetic Logic Unit)**: Executes arithmetic and logical operations. 2. **Registers**: Includes **AX**, **BX**, **CX**, **DX** (general-purpose registers), and **SI**, **DI**, **BP**, **SP** (pointer and index registers). 3. **Control Unit**: Manages operations and coordinates between CPU components. 4. **Bus Interface Unit (BIU)**: Handles memory and I/O access, and instruction fetching. 5. **Execution Unit (EU)**: Executes instructions. It supports pipelined execution and operates in **minimum** and **maximum modes**.
