Experiments were conducted by executing one
primitive of Program A, one primitive of Program B, and one primitive of Program C
[36??“38].
The sim-panalyzer [39] and XTREM [40] tools were used to estimate the power dissipation
of the microprocessor-based tag for the ARM-based cores. Sim-panalyzer is a cycleaccurate,
architecture-level power simulator built on top of the SimpleScalar simulator.
XTREM is a SimpleScalar-based power and performance simulator tailored for Intel XScale
microarchitecture. SimpleScalar??™s sim-pro?¬?le was used to obtain ARM instruction and

instruction class pro?¬?les for tag software. Because an instruction set simulator was not
available for the EISC, the application was run on the development board and the execution
time was measured by setting a pin output from low to high on each iteration.
