The next three questions refer to the following system: A certain ISA has a 32-bit word size, uses single word (32-bit) instructions, has 60 opcodes, 32 registers, and 4Gbyte of byte-addressable memory. One group of instructions in this ISA takes the form: OPCODE | DESTINATION REGISTER | SOURCE REG. | Flag | IMMEDIATE VALUE Or OPCODE | DESTINATION REGISTER | SOURCE REG. 1 | Flag | SOURCE REG. 2 A single bit in the instruction ("Flag") is used to differentiate these two addressing modes. Another group of instructions takes the form OPCODE | SOURCE/DESTINATION REGISTERI PC OFFSET Where PC Offset is the 2's complement "distance" from the current PC to the labelled location.

A computer uses a memory unit of 512 K words of 32 bits each. A binary instruction code is stored in one word of the memory. The instruction has four parts: an addressing mode field to specify one of the two-addressing mode (direct and indirect), an operation code, a register code part to specify one of the 256 registers and an address part. How many bits are there in addressing mode part, opcode part, register code part and the address part?
