How do you convert BCD to Hex?

  1. (1011001)BCD = (? )
  2. Solution:
  3. (1011001)BCD = (_______)16 Convert BCD to decimal.
  4. (1011001)BCD = (_______)10 0101. 1001. ∴ (1011001)BCD = (59)10 Convert decimal to hexadecimal.
  5. (59)10 = (_______)16 B. ↑ ↑ ∴ (59)10 = (3B)16
  6. ∴ (1011001)BCD = (3B)16
  7. (101100111)BCD = (? )
  8. Solution:

What is hex code in microprocessor?

Hexadecimal (base 16 – 0 1 2 3 4 5 6 7 8 9 A B C D E F) is used as a shortcut notation for binary numbers (0 1) because it works out nicely for 8, 16, 32, and 64 bit processors. Simple answer: Hex is encoding 4 binary digits into one hex digit, and is easier to read than strings of 0s and 1s.

Which is the main instruction used to find the 1’s complement of a number?

instruction CMA
Discussion. 8085 has an instruction CMA. This instruction complements the content of Accumulator. For 1’s complement CMA instruction is sufficient, and for 2’s complement we have to increase the number by 1 after complementing.

Which instruction adjusts 8 bit number in the accumulator to form two BCD numbers?

The DA instruction adjusts the eight-bit value in the Accumulator resulting from the earlier addition of two variables (each in packed-BCD format), producing two four-bit digits.

What is MVI in microprocessor?

MVI is a mnemonic, which actually means “Move Immediate”. With this instruction,we can load a register with an 8-bitsor 1-Bytevalue. This instruction supports immediate addressing mode for specifying the data in the instruction.

Why is 1s and 2s complement used?

No overflow : 1’s complement has no special usage for negative integers. 2’s complement makes sense because it can be used in natural addition and subtraction arithmetic without any need to change the bits. Providing that no overflow occurs, the sign bit of the result is just the right value.

What is the operation of CMA instruction in 8085 MP?

In 8085 Instruction set, logical type there is one complement instruction with the mnemonic CMA. It actually stands for “CoMplement the Accumulator”. It performs1’s complement operation on the current contents of Accumulator, and the result is stored back in the Accumulator replacing its previous contents.

What is 8bit BCD?

In other words, the BCD is a weighted code and the weights used in binary coded decimal code are 8, 4, 2, 1, commonly called the 8421 code as it forms the 4-bit binary representation of the relevant decimal digit.
