Jul 30, 2019 · Instruction type DAD rp in 8085 Microprocessor - In spite of the fact that 8085 is an 8-bit microprocessor, but there are some instructions are there available in the 8085 instruction set which can do 16-bit additions also.
Jul 30, 2019 · In 8085 Instruction set, DAD SP instruction is a special case of DAD rp instruction. In this instruction contents of HL and SP will get added and sum thus produced will get stored onto HL register pair. It occupies only 1-Byte in memory.
Apr 26, 2024 · The DAA (Decimal Adjust Accumulator ) instruction is a specific command used in some microprocessors, such as Intel 8085. The purpose of the DAA instruction is to adjust the contents of the Accumulator to represent a valid BCD (Binary-Coded Decimal) number after performing an addition operation.
Jun 27, 2020 · Execution of ‘DAD rp’ instruction. Microprocessor 8085. In 8085 Instruction set, for 16-bit addition, there is one instruction available that is DAD rp instruction. It is a 1-Byte instruction.

May 7, 2023 · Arithmetic instructions in 8085 microprocessor. Last Updated : 07 May, 2023. Arithmetic Instructions are the instructions which perform basic arithmetic operations such as addition, subtraction and a few more. In 8085 microprocessor, the destination operand is generally the accumulator.
Jul 7, 2022 · 1. Addition of 16-bit numbers using 8-bit operation: It is a lengthy method and requires more memory as compared to the 16-bit operation. Algorithm: Load the lower part of the first number in the B register. Load the lower part of the second number in A (accumulator). Add both the numbers and store.
Apr 27, 2022 · In this post, we will write programs in 8085 Assembly language for the addition of two 16-bit numbers. In program 1, eight bit addition instructions are used (ADD and ADC) and addition is performed in two steps. First lower byte addition using ADD instruction and then higher byte addition using ADC instruction.
Apr 1, 2020 · In this post, we will look at the arithmetic instructions possible in 8085. We’ll try to get an idea about how an elementary processor carries out its arithmetic instructions. Towards the end, we will look at an example to understand the practical application of these instructions.
8085 Instruction Set Page 2 Store accumulator direct STA 16-bit address The contents of the accumulator are copied into the memory location specified by the operand. This is a 3-byte instruction, the second byte specifies the low-order address and the third byte specifies the high-order address. Example: STA 4350H Store accumulator indirect
