Abstract: A processor may be built with cores that only execute some partial set of the instructions needed to be fully backwards compliant. Thus, in some embodiments power consumption may be reduced by providing partial cores that only execute certain instructions and not other instructions. The instructions not supported may be handled in other, more energy efficient ways, so that, the overall processor, including the partial core, may be fully backwards compliant.
