The memory unit of a computer has 2 M words of 32 bits each. The computer has an instruction format with 4 fields: an opcode field; a mode field to specify 1 of 8 addressing modes; a register address field to specify 1 of 8 registers; and a memory address field. Assume an instruction is 32 bits long. Answer the following:

a.How large must the mode field be?

b.How large must the register field be?

c.How large must the address field be?

d.How large is the opcode field?
