What can do 8086 microprocessor?

What can do 8086 microprocessor?

Unlike, 8085, an 8086 microprocessor has 20-bit address bus. Thus, is able to access 220 i.e., 1 MB address in the memory. As we know that a microprocessor performs arithmetic and logic operations. And an 8086 microprocessor is able to perform these operations with 16-bit data in one cycle.

What is programming model of a microprocessor?

The programming model of the 8086 is considered to be program visible because its registers are used during application programming and are specified by the instructions. Figure below illustrates the programming model of 8086 microprocessor. The multipurpose registers include EAX, EBX, ECX, EDX, EBP, EDI, and ESI.

What are the two types of instructions in 8086 processors?

8086 processors have two other instructions to access the data, such as WORD PTR – for word (two bytes), BYTE PTR – for byte. Op-code: A single instruction is called as an op-code that can be executed by the CPU.

What is the architecture of 8086?

8086 Processor Architecture The assembly level programming 8086 is based on the memory registers. A Register is the main part of the microprocessors and controllers which are located in the memory that provides a faster way of collecting and storing the data.

What are arithmetic and logic instructions in 8086?

Most Arithmetic and Logic Instructions affect the processor status register. The assembly language programming 8086 mnemonics are in the form of op-code, such as MOV, MUL, JMP, and so on, which are used to perform the operations.
