 <p class="figure">Figure 3. Resolving correct values in linked function level load analysis</p>
 <p>Thus, through periodic sampling it is possible to always retrieve the address of the interrupted execution from the PC, and in a certain proportion of cases it is also possible to retrieve the caller of the function in which the execution takes place from the LR. The proportion of those two cases is in practice dictated by the proportion of instructions executed on average before and after the first subsequent BL command within the function. When analyzing the results, this proportion can be calculated for each function as a proportion between the sampled LR values that point outside the function and the values that point inside the function. In the analysis within the Performance Investigator, this proportion is used in extrapolating the amount of callers to a certain function. It is assumed that the distribution of callers of a certain function is the same in the samples from which the caller function could not be resolved as it is within the samples in which the value could be retrieved. This is shown in Figure 3. In specific circumstances, this assumption can result in an error, mainly by multiplying &ldquo;noise&rdquo; to statistically important dimensions. This has to be taken into consideration when reading the results.</p>
