Abstract :
On the hardware side, asymmetric multicore processors present software with the challenge and opportunity of optimizing in two dimensions: performance and power. Asymmetric multicore processors (AMP) combine general-purpose big (fast, high power) cores and small (slow, low power) cores to meet power constraints. Realizing their energy efficiency opportunity requires workloads with differentiated performance and power characteristics.
