Answer:
The correct answer is 1000 MIPS.
Explanation:
Using the rule of three you can solve the needed cycles to complete 1.000.000 instructions.
1.000.000 instructions multiplied by 2 cycles, divided by 1 instruction is equal to 2.000.000 cycles to complete 1.000.000 instructions.
To find the MIPS you have to divide the frequency by the cycles needed to complete 1.000.000 instructions.
MIPS = 2GHZ / 2.000.000 cycles = 1000 MIPS.
