How can add two numbers in assembly language 8086?

Algorithm –

1. Load 0000H into CX register (for carry)
2. Load the data into AX(accumulator) from memory 3000.
3. Load the data into BX register from memory 3002.
4. Add BX with Accumulator AX.
5. Jump if no carry.
6. Increment CX by 1.
7. Move data from AX(accumulator) to memory 3004.
8. Move data from CX register to memory 3006.

Why is assembly language faster?

Actually, in most cases, writing programs in assembly language, the programmers put more effort in writing smaller and readable code, than in writing faster code. But as a result, these programs always perform faster than their HLL counterparts.

When would you use assembly language?

Today, assembly language is used primarily for direct hardware manipulation, access to specialized processor instructions, or to address critical performance issues. Typical uses are device drivers, low-level embedded systems, and real-time systems.

What can I do with assembly language?

Today, assembly language is still used for direct hardware manipulation, access to specialized processor instructions, or to address critical performance issues. Typical uses are device drivers, low-level embedded systems, and real-time systems.

What is instruction in assembly language?

An instruction is a statement that is executed at runtime. An x86 instruction statement can consist of four parts: Label (optional) Instruction (required) Operands (instruction specific)

What are the basics of assembly programming?

The basics of programming in assembly, the design of the processor, registers, memory, instruction, and use of assembly language within C++ and Delphi. 1. Introduction to assembly

What is the advantage of assembly language for converting numbers?

Such conversions, however, have an overhead, and assembly language programming allows processing numbers in a more efficient way, in the binary form. Decimal numbers can be represented in two forms −

Why do we convert decimal numbers to binary in assembly language?

Such conversions, however, have an overhead, and assembly language programming allows processing numbers in a more efficient way, in the binary form. Decimal numbers can be represented in two forms − ASCII form; BCD or Binary Coded Decimal form; ASCII Representation. In ASCII representation, decimal numbers are stored as string of ASCII characters.

What is the purpose of low-level assembly language?

So, the low-level assembly language is designed for a specific family of processors that represents various instructions in symbolic code and a more understandable form. How a program accesses external devices.
