What is the difference between a conditional jump and an unconditional jump?
Unconditional Jump Instructions: Transfers the program sequence to the described memory address. Conditional Jump Instructions Transfers the program sequence to the described memory address only if the condition in satisfied.
What all are the conditional jump instruction in 8085?
Conditional and Unconditional JUMP instructions in 8085 Microprocessor
| Opcode | Description | Flag Status |
|---|---|---|
| JC | Jump on Carry | CY=1 |
| JNC | Jump on no Carry | CY=0 |
| JP | Jump on positive | S=0 |
| JM | Jump on minus | S=1 |
How many jump instruction are there in 8085 microprocessor?
Jump instructions are 2 types: Unconditional Jump Instructions and Conditional Jump Instructions. (a) Unconditional Jump Instructions: Transfers the program sequence to the described memory address.
What is the difference between the JA and JNBE instructions?
Assuming you mean the ja and jnbe mnemonics in x86 assembly: There’s no difference; they are two different mnemonics for the exact same instruction.
What is conditional jump discuss various conditional jump instructions with examples?
The following table shows the list of conditional jump instructions with their meanings….Conditional JUMP instructions in 8085 Microprocessor.
| Opcode | Description | Flag Status |
|---|---|---|
| JNZ | Jump on no zero | Z=0 |
| JPE | Jump on parity even | P=1 |
| JPO | Jump on parity odd | P=0 |
What is the difference between jump and branch?
There is another difference between branch and jump instructions. Jump instructions specify an absolute address which the PC will be set to, whereas branch instructions offset the address in the program counter.
What are the jump instructions in 8085 microprocessor?
Conditional and Unconditional JUMP instructions in 8085 Microprocessor Microprocessor 8085 In 8085 Instruction set,there are a set of jump instructions, which can transfer program control to a certain memory location. So after these branching mnemonics we shall have to mention 16-bit target address of the location.
How many mnemonics are there for jump instruction in 8085?
Under unconditional jump instructions there is only one mnemonic i.e. JUMP. But under conditional Jump instructions we are having 8 different mnemonics. We know that there are 5 flag bits in 8085 Flag register. They are S, Z,P, Cy, AC. Out of them only on AC flag bit, there is no jump instruction.
What is push RP instruction in microprocessor 8085?
Microprocessor 8085 In 8085 Instruction set, PUSH rp instruction stores contents of register pair rp by pushing it into two locations above the top of the stack. rp stands for one of the following register pairs. rp = BC, DE, HL, or PSW As rp can have any of the four values, there are four opcodes for this type of instruction.
What are hardware and software interrupts in 8085?
Hardware and Software Interrupts – When microprocessors receive interrupt signals through pins (hardware) of microprocessor, they are known as Hardware Interrupts. There are 5 Hardware Interrupts in 8085 microprocessor. They are – INTR, RST 7.5, RST 6.5, RST 5.5, TRAP
