Define opcode and operands, Computer Engineering

Assignment Help:

Q. Define Opcode and Operands?

The most common fields which are found in instruction formats are:

Opcode: (What operation to perform?) 

  • An operation code field called opcode that specifies operation to be performed.

Operands: (Where are the operands?)

  • An address field of operand on that data processing is to be performed.
  • An operand can reside in the memory or a processor register or can be combined within the operand field of instruction as an immediate constant. Thus a mode field is requiredwhich specifies the way the operand or its address is to be determined.
