What do you mean by instruction set?
An instruction set is a group of commands for a CPU in machine language. The term can refer to all possible instructions for a CPU or a subset of instructions to enhance its performance in certain situations. Some instructions are simple read, write and move commands that direct data to different hardware.
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 is instruction and types of instruction?
A computer must have the following types of instructions: Data transfer instructions. Data manipulation instructions. Program sequencing and control instructions. Input and output instructions.
What is instruction set and its types?
The instruction set provides commands to the processor, to tell it what it needs to do. The instruction set consists of addressing modes, instructions, native data types, registers, memory architecture, interrupt, and exception handling, and external I/O.
What is instruction set of 8085?
Instruction Set of 8085 An instruction is a binary pattern designed inside a microprocessor to perform a specific function. The entire group of instructions that a microprocessor supports is called Instruction Set. 8085 has 246 instructions. Each instruction is represented by an 8-bit binary value. These 8-bits of binary value is called Op-Code or
How many flip-flops are there in an 8085 microprocessor?
There is a set of five flip-flops which indicate status (condition) arising after the execution of arithmetic and logic instructions. These are: The symbol and abbreviations which have been used while explaining Intel 8085 instructions are as follows: 16-bit address of the memory location. One of the register pairs.
What is instruction set in microprocessor?
