UniPhier is the strategic integrated platform for digital consumer applications and it is introduced into very wide range of consumer products, mobile applications, personal AV applications and car/home AV applications. In this paper, the authors describe the various low power techniques for mobile application SoCs based on the integrated platform \"UniPhier\". To minimize System-on-Chip (SoC) power dissipation, hierarchical approaches from UniPhier SoC level, UniPhier processor level, IPP (Instruction Parallel Processor) level, and circuit level are adopted. As SoC level, well functionally isolated 5 major units of UniPhier SoC architecture and dedicated stream DMA controller which can minimize CPU load and memory access.
