In this paper, the authors propose a new way to save energy in adaptive processors. According to an execution context the custom instruction set of an adaptive processor is selectively 'Muted' at run time and thus the energy efficiency is significantly increased. Implemented are multiple so called 'Muting modes' each leading to particular leakage energy savings. A key challenge of this paper is to determine which of the muting modes are beneficial for which part of the custom instruction set in a specific execution context.
