Recent research has shown that dynamic information regarding instruction criticality can be used to increase microprocessor performance. Critical path information can also be used in processors to achieve a better balance of power and performance. This paper uses the output of a dynamic critical path predictor to decrease the power consumption of key portions of the processor without incurring a corresponding decrease in performance. The optimizations include effective use of functional units with different power and latency characteristics and decreased issue logic power.
