A processor has word-addressable memory with all instructions of length 1 word (which is equal to 4 bytes). At a given point in time, the current instruction being executed has an operand field with the value 7C30. At this time, suppose the Program Counter contains the address 49A072, the register R3 contains the value 5600, and the register R4 contains the value 3A. All addresses and values above are in hex. For each of the following addressing modes, find the effective address of the operand:. a) Direct mode
b) PC-relative mode
c) Displacement mode with base register R3 and displacement given by the operand field
d) Indexed mode with index register R4 and base address given by the operand field
