Power and Temperature Estimation for Soft-core Processor Task at the SystemC/TLM

摘要

In order to meet the growing computation requirements of modern embedded applications, systems on chip are becoming one of the most appropriate solutions while maintaining a low power profile. Consequently, early estimations for power and temperature must be done at high level models that offer a better trade-off between accuracy and time. The Transaction Level Modeling with the SystemC presents the suitable approach for simulating the embedded software on proposed hardware architectures.Power estimation can be done as far as the temperature computations are available. In these terms, the one in question is obtained by coupling the SystmeC/TLM model with the ATMI (Analytical Model of Temperature in Microprocessors) library. For this task, the present paper will focus on power and especially thermal behavior, since the static power starts increasing as the technology node is decreasing.We explore in our work three applications based on the game of life to distinguish the effect of the software on the minimal hardware simulated by the LIBTLMPWT (Library of Power and Temperature at the Transaction-Level-Modeling) library used. This one spotlights on a soft-core processor `Microblaze' as a complex architecture compared to the virtual platforms done.
