Energy Consumption is a leading criterion to take into ac-
count in the design of multiprocessor systems on chip (MP-
SoC). In this paper, we present a solution to estimate the
energy consumption early inMPSoC design in order to nd a
good performance/energy trade-o in the design
ow. This
solution is based on the injection of consumption estimators
between the hardware components during the co-simulation
of a system at the CABA (Cycle Accurate Bit Accurate)
level. These estimators are designed using a design frame-
work and the corresponding SystemC code is automatically
generated thanks to a model driven approach. Our solution
oers an energy estimation framework without changing the
IP(Intellectual Property)source codes, using standalone es-
timation modules, which allows their reuse. The accuracy
of this approach is checked by integrating the consumption
estimation in the simulation of signicant applications.
