60 the tool effectively runs on the CPU. The *Noise* column is the sum of
61 all noise that the tool observed, and the *% CPU Aval* is the relation
62 between the *Runtime* and *Noise*.
64 The *Max Noise* column is the maximum hardware noise the tool detected in a
65 single period, and the *Max Single* is the maximum single noise seen.
67 The *HW* and *NMI* columns show the total number of *hardware* and *NMI* noise
71 *86 us* of noise during the entire execution, leaving *99.99997 %* of CPU time
73 noise to the application, but it was certainly caused by more than one single
74 noise, as the *Max Single* noise was of *3 us*. The CPU has *HW noise,* at a
