branch and call instructions in 8086

The aaa and daa instructions modify the result of a binary addition to correct it for ASCII or decimal arithmetic.
For example, to add two BCD values, you would add them as though they were binary numbers and then execute the daa instruction afterwards to correct the results.

What are branch and call instructions?

Branching instructions refer to the act of switching execution to a different instruction sequence as a result of executing a branch instruction.
The three types of branching instructions are: Jump (unconditional and conditional) Call (unconditional and conditional) Return (unconditional and conditional)_{7 mai 2023}

What are branching instructions in 8086?

Branch instructions in this 8086 microprocessor are that jumps to another part of the program without executing in a sequential manner.
Eg: for loop in other programming languages. goto instruction in c language.
Mainly there are two types of branch instructions in 8086 which are further classified into two types each.

What is call instruction in 8086?

The CALL instruction is used whenever we need to make a call to some procedure or a subprogram.
Whenever a CALL is made, the following process takes place inside the microprocessor: The address of the next instruction that exists in the caller program (after the program CALL instruction) is stored in the stack.
