What are the main features of 8086 microprocessor?
1) The 8086 is a 16-bit microprocessor. The term “16-bit” means that its arithmetic logic unit, internal registers and most of its instructions are designed to work with 16-bit binary words. 2) The 8086 has a 16-bit data bus, so it can read data from or write data to memory and ports either 16 bits or 8 bits at a time.
What are the additional features of 8086 MP over 8085 MP?
There are some advantages of 8086 over 8085 e.g. more memory, faster clock speeds, backward compatibility, sort of better math etc. some of them are as follows: 8086 is 16 bit microprocessor whereas 8085 is 8 bit microprocessor. 8086 has 20 bit address bus while 8085 has 16 bit address buss.
Which of the following segment registers contains data in 8086 MP?
8086 Segment Registers 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. They deal with selecting blocks (segments) of main memory.
Which of the following is not a features of 8086 Mcq?
Which of the following is not a Features of 8086? D. It has 512 vectored interrupts. Explanation: It has 256 vectored interrupts is true Features of 8086.
What are the functional parts of 8086 CPU?
8086 Microprocessor is divided into two functional units, i.e., EU (Execution Unit) and BIU (Bus Interface Unit)….BIU (Bus Interface Unit)
- CS − It stands for Code Segment.
- DS − It stands for Data Segment.
- SS − It stands for Stack Segment.
- ES − It stands for Extra Segment.
What are the instruction set of 8086?
Branch Instructions
| Instruction | Description |
|---|---|
| INTO | Software interrupts to indicate overflow after arithmetic operation. |
| LOOP | Jump to defined label until CX = 0. |
| LOOPZ/LOOPE | Decrement CX register and jump if CX ≠ 0 and ZF = 1. |
| LOOPNZ/LOOPNE | Decrement CX register and jump if CX ≠ 0 and ZF = 0. |
