What is instruction of 8085 write the type of instruction?
Arithmetic Group
| Instruction Set | Explanation | Flags |
|---|---|---|
| ADI data [A] ← [A] + data | Add immediate data to accumulator | All |
| ACI data [A] ← [A] + data + [CS] | Add with carry immediate data to accumulator | All |
| DAD rp [H-L] ←[H-L] + [rp] | Add register paid to H-L pair | CS |
| SUB r [A] ←[A]-[r] | Subtract register from accumulator | All |
What is instruction and its type?
The instruction types include load and store with reservation, synchronization, and enforce in-order execution of I/O. They are especially useful for multiprocessing. Flow Control Instructions – These include branch, Condition-Register logical, trap, and other instructions that affect the instruction flow.
What are the two types of instruction?
Types of Instruction
- Direct instruction. The Direct instruction strategy is highly teacher-directed and is among the most commonly used.
- Indirect instruction.
- Independent study.
- Interactive instruction.
- Experiential Learning.
What are different parts of an instruction?
17. Instruction Components
- Instruction in memory has two parts: opcode and operands.
- The opcode identifies the operation that instruction does.
- The operands are subjects of the operation, such as data values, registers, or memory addresses.
Which type of instruction push is?
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. As rp can have any of the four values, there are four opcodes for this type of instruction. It occupies only 1-Byte in memory.
What is the function of push instruction?
The PUSH instruction increments the stack pointer and stores the value of the specified byte operand at the internal RAM address indirectly referenced by the stack pointer. No flags are affected by this instruction.
What is the output of push al?
1 Answer. On 8086 push decrements the SP register by 2 and then writes a 16 bit value at the memory pointed to by the SP register. You cannot write push al because AL is an 8 bit value and push requires a 16 bit value.
What is MOV PLC?
Move Instruction (MOV) The MOV instruction moves a Source value to a Destination location. The symbol for the move command is illustrated above. The MOV command. is an output instruction that moves a copy of a value from a Source to a desired Destination.
