Resum
The issue logic of a superscalar processor consumes a large amount of static and dynamic energy. Furthermore, its power density makes it a hot-spot requiring expensive cooling systems and additional packaging. This paper presents a novel approach to energy reduction that uses compiler analysis communicated to the hardware, allowing the processor to dynamically resize the issue queue, fitting it to the available ILP without slowing down the critical path. Limiting the entries available reduces th...
