Title
Software power peak reduction on smart card systems based on iterative compiling
Abstract
RF-powered smart cards are widely used in different application areas today. The complexity and functionality of smart cards is growing continuously. This results in a higher power consumption. The power consumed is heavily depending on the software executed on the system. The power profile, especially the power peaks, of an executed application influence the system stability. If the power consumed by such a device exceeds the power provided by the RF-field a reset can be triggered by the power control unit or otherwise the chip may stay in an unpredictable state. Flattening the power profile can thus increase the stability of a system. We present an optimization system which intends to eliminate critical peaks after the analysis of the power profile of an executed application. In an iterative compile process an optimal tradeoff between power and performance has to be found. This is achieved by selecting or deselecting different optimization passes on the intermediate language level of the compiler.
