FAQs On Computer Organization Instruction Formats

1. Does Instruction Format affects Efficiency of Machines?

Instruction Format has several impact on Instruction Execution, Memory Usage and Density of Code. It requires fewer mwmory access, that ultimately results in faster execution.

2. Does single architecture supports multiple Instruction Format?

It is possiible for some architectures to allow multiple instruction format to run parallely. There can be variable length instruction encoding or different addressing modes.

3.What is the purpose of an opcode in an instruction format?

The opcode specifies the operation to be performed by the CPU. It tells the CPU what action to take with the operands provided in the instruction.

4.What are operands in an instruction format?

Operands are the data on which the operation specified by the opcode is performed. These can be registers, memory addresses, or immediate values.

5.What is the significance of addressing modes in instruction formats?

Addressing modes specify how operands are accessed. Common addressing modes include direct, indirect, indexed, and immediate. They affect the interpretation of operand fields.

In computer organization, instruction formats refer to the way instructions are encoded and represented in machine language. There are several types of instruction formats, including zero, one, two, and three-address instructions.

Each type of instruction format has its own advantages and disadvantages in terms of code size, execution time, and flexibility. Modern computer architectures typically use a combination of these formats to provide a balance between simplicity and power.
