Salient points about addressing mode, Computer Engineering

Assignment Help:

Salient points about addressing mode are:

This addressing mode is employed to initialise value of a variable.
Benefit of this mode is that no extra memory accesses are needed for executing the instruction.
Size of instruction and operand field is limited. So the type of data specified under this addressing scheme is also restricted. E.g. if an instruction of 16 bits employs 6 bits for opcode and 2 bits for addressing mode then 10 bits can be employed to specify an operand. So 210 possible values only can be assigned.
