True/False about MIPS questions!

Part b) Answer with True/False for each of the statements below. Statements about MIPS64... 1) All the instructions of MIPS32 are available in MIPS64. 2) In MIPS64, it is acceptable to use 64-bit operations for 32-bit data (eg: using DADD for 32-bit variables) 3) The instruction AND' is used for 32-bit and 64-bit variables. 4) In MIPS64, the register FO is always equal to zero. 5) The 'convert' (CVT) instructions can be applied on the GPRs and on the FPRs. Statement about supporting exceptions... 6) The Exception Program Counter (EPC) holds the address of the instruction that encountered the exception en an exception occurs, the PC is rewinded by 4 before being saved in EPC. 7) Wh 8) The Cause register indicates to the OS how to respond to the exception/interrupt event (eg: shut down the program, ignore the overflow); the hardware decides how to respond and passes this message to the OS. When an exception occurs, we jump to address 0x80000180 which is the address of the running program so that it restarts. ) 10) The control state machine should be modified to support the interrupt/exceptions events response
