What is the need of addressing mode?

The various addressing modes that are defined in a given instruction set architecture define how machine language instructions in that architecture identify the operand (or operands) of each instruction. An addressing mode specifies how to calculate the effective memory address of an operand by using information held in registers and/or constants contained within a machine instruction or elsewhere.


List and briefly define the possible states that define an instruction execution?

The possible states that define an instruction execution are as follows: Instruction address calculation - Determine the address of the next instruction to be executed. Instruction fetch - Read instruction from its memory location into the processor. Instruction operation decoding - Analyze instruction to determine type of operation to be performed and operand to be used. Operand address calculation - If the operation involves reference to an operand in memory or available via I/O, then determine the address of the operand. Operand fetch - Fetch the operand from memory or read it in from I/O. Data operation - Perform the operation indicated in the instruction. Operand store - Write the result into memory or out to I/O.


What determines the size of a General purpose register in a microprocessor system?

The size of a general-purpose register in a microprocessor system is primarily determined by the architecture of the processor, particularly its instruction set architecture (ISA). Common architectures, such as x86 and ARM, define specific register sizes, typically ranging from 32 bits to 64 bits or even 128 bits in advanced systems. Additionally, the desired performance, data handling capacity, and compatibility with operating systems and applications also influence the choice of register size in a microprocessor design.


What is Op code and Operand?

An opcode (operation code) is a part of an instruction in machine language that specifies the operation to be performed, such as addition, subtraction, or data movement. The operand, on the other hand, is the part of the instruction that provides the necessary data or addresses required for the operation, indicating the target of the operation or the data to be manipulated. Together, the opcode and operand define the specific action and the data involved in machine-level programming.
