Standard Deviation
Deviation from the mean of state count. The following
equation is used to calculate standard deviation:
Where:
N
Number of traces in the measurement.
mean
Average number of states in the range per trace.
S
sumq
Sum of squares of states in the range per trace.
Symbols Within Range
Names of other symbols that identify addresses or
ranges of addresses within the range of this symbol.
Additional Symbols for Address
Names of other symbols that also identify
this address.
Note that some compilers emit more than one symbol for certain addresses. For
example, a compiler may emit "interrupt_sim" and "_interrupt_sim" for the first
address in a routine named interrupt_sim. The analyzer will show the first symbol
it finds to represent a range of addresses, or a single address point, and it will show
the other symbols under either "Symbols within range" or "Additional symbols for
address", as applicable. In the "interrupt_sim" example, it may show either
"interrupt_sim" or "_interrupt_sim" to represent the range, depending on which
symbol it finds first. The other symbol will be shown below "Symbols within
range" in the report. These conditions appear particularly in default measurements
that include all global and local symbols.
Relative and Absolute Counts
Relative count is the total number of states
associated with the address ranges in the performance measurement. Relative time
is the total amount of time associated with the address ranges in the performance
measurement. The absolute counts are the number of states or amount of time
associated with all the states in all the traces.
