The memory unit of a computer has 128K words of 32 bits each. The computer has an instruction format with four fields: an operation code field, a mode field to specify one of 5 addressing modes, a register address field to specify one of 6 processor registers, and a memory address. Specify the number of bits in each field of the instruction if it occupies one memory word. ◆ bits ◆ bits bits ◆ bits Op-code Addressing Mode Register Address Memory Address
