We conducted a mobile platform specific software and system optimization for an open-source multimedia player, MPlayer. The target system is based on the Intel XScale PXA270 CPU. The optimization process consists of 4 steps: utilizing the color conversion hardware, adopting SIMD optimization, increasing the external memory access speed, and exploiting the internal memory. At each optimization step, we measured the execution time, cache miss characteristics, and power consumption. The… CONTINUE READING
