Computer architecture instruction format

What are the 3 types of instructions?
In this topic, we will learn what computer instructions are and the three types of instructions-memory reference instruction, register reference instruction, and input-output instruction..
What is instruction formats in computer architecture?
The data on which operations are performed are stored in the computer.
Different computers have their own set of instructions.
The CPU or processor takes all these instructions from memory and decodes the bits to carry out the instructions.
The layout of bits of instruction is called an instruction format..
What is the format of machine instruction?
A machine instruction is a simple program instruction in binary form.
It comprises several bytes in memory that tells the processor how to perform one machine operation.
The microprocessor decodes and executes Types of machine instruction without further processing..
What is the format of register to register instruction?
RR (Register–to–Register) Format
This is a two–byte instruction of the form OP R1,R2.
The first byte contains the 8–bit instruction code.
The second byte contains two 4–bit fields, each of which encodes a register number.
This instruction format is used to process data between registers..
What is the structure of instructions in computer architecture?
Computer instruction is divided into groups called fields.
Storage - reference instruction, Registry - reference instruction, and Input-Output instruction are the three types of instruction codes in a basic system..
Where is instruction stored in computer?
Instructions are stored in memory and the contents of the PC register are used as the starting address from where the next to be executed instruction is read.
Because the length of an 68k instruction is bytes can vary decoding and reading the instruction from memory (steps 1 and 2) is an iterative process..
Why use instruction set architecture?
Why the ISA Is Important? Understanding what the instruction set can do and how the compiler makes use of those instructions can help developers write more efficient code.
It can also help them understand the output of the compiler which can be useful for debugging..

Storage - reference instruction, Registry - reference instruction, and Input-Output instruction are the three types of instruction codes in a basic system.
I-Type instructions, or Immediate instructions, can be either Load/Store operations, Branch operations, or Immediate ALU operations.
In these instructions, one two register file locations are specified as well as a 16-bit immediate value which may be used as an operand or an address.
In RISC, the length of the instruction format is fixed.
It took one-word memory.
The fixed size of the instruction format benefits the program counter as it knows that the next instruction starts from where due to the fixed length of all instructions.
In RISC, each instruction requires only one clock execution cycle.
RR (Register–to–Register) Format
This is a two–byte instruction of the form OP R1,R2.
The first byte contains the 8–bit instruction code.
The second byte contains two 4–bit fields, each of which encodes a register number.
This instruction format is used to process data between registers.

The instruction formats are a sequence of bits (0 and 1). These bits, when grouped, are known as fields. Each field of the machine provides specific information to the CPU related to the operation and location of the data. The instruction format also defines the layout of the bits for an instruction.
