-In the chart above, it can be seen in a general way that in both cases, the frame-rate reaches the expected value of 25 fps and then remains stable.
+In the chart above, it can be seen that when vpe coprocessor is used, the expected value of 30 fps is achieved and then frame-rate maintains stable. In the other case, when no hardware acceleration is used, the expected value of 30 fps can not be achieved, and it shows an unstable behavior between 24 and 25 fps.
