The first two bytes of a 4M x 16 main memory have the following Hex values: Byte 0 is FE Byte 1 is 04 If these bytes hold a 16-bit two's complement integer, what is its actual decimal value if: a) Memory is big endian? b) Memory is little endian? 2. The memory unit of a computer has 2M Words of 32 bits (or 4 bytes) each. The computer has an instruction format with 4 fields: an opcode field; an addressing mode field to specify 1 of 6 addressing modes; a register address field to specify one of 7 registers; and a memory address field. Assume an instruction is 32 bits long. Answer the following: How large must the addressing mode field be? How large must the register field be? How large must the address field be? How large is the opcode field?

1. T/F - if (B)=006000 (PC)=003600 (X)=000090, for the machine instruction 0x032026, the target address is 003000.2. T/F – PC register stores the return address for subroutine jump.3. T/F – S register contains a variety of information such as condition code.4. T/F – INPUT WORD 1034 – This means Operating system should reserve 1034 bytes in memory5. T/F - In a two pass assembler, adding literals to literal table and address resolution of local symbol are done using first pass and second pass respectively.
