Efficient embedded system algorithm mapping

For many embedded systems it is critical to reduce power and area consumption to the absolute minimum. For example, in hearing aid processing, the processors must be made small enough to fit the smallest ear canal and also provide sufficient battery life for approximately one week of operation. Implantable Cardioverter Defibrilator ICD devices require much longer lifetime but significantly less processing. Accordingly, they must have extremely low leakage and maintain sufficient reserve to provide a therapeutic action - in the case of an ICD, a pulse of up to 10J. In the absence of significant activations, these devices require a battery life of 5 years.
