What is instruction set format?

Instruction format describes the internal structures (layout design) of the bits of an instruction, in terms of its constituent parts. An Instruction format must include an opcode, and address is dependent on an availability of particular operands.

What is instruction code format?

An instruction code is a group of bits that instruct the computer to perform a specific operation. • The operation code of an instruction is a group of bits that define operations such as addition, subtraction, shift, complement, etc.

Where is instruction set stored?

You can see it as , instruction set is stored in the control unit . control unit is a hardware logic circuit which indeed is a silicon chip ( semiconductor device ), designed in such a way that it responds to certain inputs (memory instructions ) to produce meaningful control signals for the other CPU components .

What is arithmetic instruction?

The arithmetic instructions define the set of operations performed by the processor Arithmetic Logic Unit (ALU). The arithmetic instructions are further classified into binary, decimal, logical, shift/rotate, and bit/byte manipulation instructions.

What is instruction format and its types?

An instruction format defines layout of bits of an instruction, in terms of its constituent parts. An instruction format must include an opcode and implicitly or explicitly, zero or more operands. Each explicit operand is referenced using one of addressing modes.
