2. Consider the following MIPS code segment being executed on machine M: lw $t1, 10(812) srl $t1, $t1, 16 lui $13 0x7FFF ori St3 0xFFFF Loop: xor $14, $t1, St3 add $t1, $t1, St4 all Sti. Sti. 16 bgt St1, Szero, Loop sw $t1, 1000(313) Assume M has a clock frequency is 3.5 GHz. Also, assume that 1v needs 5 clock cycles, su 4 clock cycles, bne 2 clock cycles, and all other instructions need 3 clock cycles to execute. Calculate the total amount of CPU-time (in nanoseconds) required to execute the above code.
