How can I get 16 bit number in 8086?

8086 program to Print a 16 bit Decimal number

  1. load the value stored into register.
  2. divide the value by 10.
  3. push the remainder into the stack.
  4. increase the count.
  5. repeat the steps until the value of the register is greater than 0.

  7. pop the stack.

How can I add two numbers in 8086?

8086 program to add two 8 bit BCD numbers

  1. Load data from offset 500 to register AL (first number)
  2. Load data from offset 501 to register BL (second number)
  3. Add these two numbers (contents of register AL and register BL)
  4. Apply DAA instruction (decimal adjust)
  5. Store the result (content of register AL) to offset 600.

How do you add two numbers in assembly language?

Algorithm –

  1. Load the first number from memory location 2050 to accumualtor.
  2. Move the content of accumulator to register H.
  3. Load the second number from memory location 2051 to accumaltor.
  4. Then add the content of register H and accumulator using “ADD” instruction and storing result at 3050.

How do I put two 64-bit numbers on a 32 bit machine?

Adding two 64-bit numbers cannot be done with a single instruction like addition for 32-bit numbers. The addition must be done in two stages – first the lower 32 bits and then the upper 32 bits. The result of the two lower 32 bits is stored in the lower 32 bits of the result.

How can I add two 32 bit numbers in 8085?

  1. Start the program by loading the first data into Accumulator.
  2. Move the data to a register (B register).
  3. Get the second data and load into Accumulator.
  4. Add the two register contents.
  5. Check for carry.
  6. Store the value of sum and carry in memory location.
  7. Terminate the program.

What is the 64 bit limit?

Limits of processors In principle, a 64-bit microprocessor can address 16 EBs (16 × 10246 = 264 = 18,446,744,073,709,551,616 bytes, or about 18.4 exabytes) of memory. However, not all instruction sets, and not all processors implementing those instruction sets, support a full 64-bit virtual or physical address space.

When two 16-bit words are multiplied by the processor where the results are stored?

MUL is used to multiply two 16-bit numbers. HLT is used to stop the program. AX is an accumulator which is used to store the result. BX, DX are general purpose registers where BX is used for multiplication and DX is used for result.

How can I take 16-bit input in 8086?

Explanation:

  1. load the value stored into register.
  2. divide the value by 10.
  3. push the remainder into the stack.
  4. increase the count.
  5. repeat the steps until the value of the register is greater than 0.
  6. until the count is greater than zero.
  7. pop the stack.
  8. add 48 to the top element to convert it into ASCII.

How can I add two 16 bit numbers in 8051?

As there is only one 16-bit Register in 89C51, 16-bit addition is performed by using ADDC instruction twice, i.e. adding LSD first and MSD next. DATAM1 – 12; DATAM2 = 56.

How can I store 16 bit data in 8051?

1 Answer. getpointer: rl a mov r2, a add a, #5 ; skip all insts after 1st movc and 1 byte movc a, @a+pc xch a, r2 ; 1-byte inc a ; 1-byte ; skip all instrs after 2nd movc movc a, @a+pc ; 1-byte ret ; 1-byte mytable: I hope I got it right.

What is DB in 8051?

DB (define byte) The DB directive is the most widely used data directive in the assembler. It is used to define the 8-bit data. When DB is used to define data, the numbers can be in decimal, binary, hex, or ASCII formats.

What is DB assembler?

The DB statement initializes memory with one or more byte values. expression is a byte value that is stored in memory. Each expression may be a symbol, a string, or an expression. The DB statement may be specified only within a code or const segment. An error is generated if it is used in a different segment.

What is DB in assembly?

In assembly language, we use “db” (data byte) to allocate some space, and fill it with a string. It’s a good idea to explicitly write the storage size, which is BYTE for a normal string.

Which pin is set to be 1 if we are sending some data to be displayed on LCD?

enable pin

What is role of Rs pin in LCD?

There are two very important registers inside the LCD. The RS pin is used for the selection of these registers. If RS=0, the instruction command code register is selected, which allows the user to send commands for the LCD such as clear display, cursor at home, and so on.
