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.
