What is an opcode and operand in an instruction set? In an instruction set, an opcode (operation code) is the portion of a machine language instruction that specifies the operation to be performed. It's like the verb in a sentence. On the other hand, an operand is the part of the ins...
an operand in an addition operation might be referred to as theaddendorsummand, and an operand in a multiplication operation might be called thefactorormultiplier. If multiplier is used, it typically refers to the second operand in the multiplication...

Each primitive is associated with a specific operation code (opcode). An opcodeis the binary equivalentof the primitive that tells the processor what operation to carry out. The opcode is typically accompanied byoperands, which represent the data to be manipulated by the primitive. Operands are de...
What Is an Instruction? An instruction is a defined piece of functionality that a processor can execute. An operation is typically displayed with a short form instruction name. The actual instruction is encoded as a short opcode. Many operations need to perform their operation on some data. The...
The instructions consist of a certain number of bits. In an eight-bit instruction, for example, the first 4-bit part tells the processor what to do, while the second 4-bit part tells it what data to use. We call the first and second 4-bit parts theopcodeand theoperandrespectively. ...
Data: Three parallel buses are contained by the ALU, which include two input and output operand. These three buses handle the number of signals, which are the same. Opcode: When the ALU is going to perform the operation, it is described by the operation selection code what type of operatio...
A computer has a 32-bit instruction word broken into fields as follows: opcode, six bit; two register fields, five bits each; and one immediate operand/register field, 16 bits. a) What is the maximum An IPv6 address is made up of how many bits? What...
$opcode:ident $($operands:expr),*; The next problem is that macro matchers cannot look ahead or backtrack, so $label and $opcode are ambiguous here. If we write an identifier, it could be either a label or an opcode and we won’t know until we read the next token to see if it...
In computing terms the difference between mnemonic and opcode is thatmnemonicis the textual, human-readable form of an assembly language instruction, not including operands whileopcodeis a mnemonic used to refer to a microprocessor instruction in assembly language. ...
