Suppose a computer has 32-bit instructions. The instruction set consists of 64 different operations. All instructions have an opcode and two address fields (allowing for two addresses). The first of these addresses must be a register direct address, and the second must be a memory address. Expanding opcodes are not used. The machine has 16 registers. How many bits can be used for the memory address?
