Feb 21, 2024 · Opcodes are represented as binary patterns in assembly language, while operands can be various data types, including registers, memory addresses, immediate values, or pointers. Opcodes, such as arithmetic calculations or …

Specifies instructions that can executed by a CPU/processor in machine code, eg in an instruction like "move the value 3 to the memory address X", the opcode is move. operandData that is...

Jun 8, 2018 · Opcode is the first part of an instruction which tells the computer what function to perform. Operand is the second part of the instruction.

Nov 2, 2023 · Operand is a value or reference on which an operation is performed, while an opcode is the part of a machine language instruction that specifies the operation to be performed. In computer architecture, an operand is a term used to …

May 30, 2024 · The opcode specifies the operation for the processor to execute, while operands are the values that the operation uses. For example, in the instruction ADD R1, R2, R3, ADD is the opcode and R1, R2, R3 are the operands. Understanding the distinction between these two components is crucial for grasping machine language instructions.

Mar 14, 2022 · Opcode containing 4 bits (for DP) and 6 bits (for DT) indicates the type of operation that the instruction performs. (Ex: Addition, Subtraction, etc. in case of DP and Load or Store in case of DT). Rn containing 4 bits gives the number of …

May 7, 2020 · What is the difference between opcode and mnemonics? 3 Answers. Usually opcode refers to the type of operation (ADD), and register B is an operand. However, with a fixed and small number of operands, the same operation can have different opcode for all possible operands. A mnemonic is a human readable name that helps you remember the instructions.

For example, in the instruction "ADD A, B," the opcode is "ADD," indicating that the CPU should perform an addition operation. On the other hand, an operand is a value or data that is used by the CPU in conjunction with the opcode to perform the desired operation.

The opcode is a short code which indicates what operation is expected to be performed. Each operation has a unique opcode. The operand, or operands, indicate where the data required for the operation can be found and how it can be accessed (the addressing mode, which is …

In assembly language mnemonic form an opcode is a command such as MOV or ADD or JMP. For example. The opcode is the MOV instruction. The other parts are called the 'operands'. Operands are manipulated by the opcode. In this example, the operands are the register named AL and the value 34 hex.
