Question: The instruction format below is 1 8 bits long. It provides 8 bits for the opcode and the rest is allocated to memory addresses. 0

The instruction format below is 18 bits long. It provides 8 bits for the opcode and the rest is allocated to memory addresses.
017
opcode Address
How many words of memory can be directly addressed with this format?
Re-design the instruction format to optimize the number of opcode, given the fact that the processor has only 7 different opcode to work with. What the new number of bits provided for the opcode ? what is the implication on memory storage?
