摘要: Systems, methods, and computer programs are disclosed for controlling power efficiency in a multi-processor system. The method comprises determining core stall time due to memory access one of plurality cores A execution is determined the cores. ratio versus calculated. dynamically scales frequency vote bus based on time.
