In this paper we present the ITRI System-Level Power Analysis Platform, an electronic system level (ESL) virtual platform for evaluating smart mobile device architecture with real-world workloads. The virtual platform has integrated many ESL IP models of major components that are indispensable in mobile SoC design, including CPU, GPU, Video Encoder, Video Decoder, ISP, LPDDR3 controller, NoC and LCDC. The ESL IP models are designed based on C/SystemC programming language and are compatible with the standard TLM 2.0 interface with non-blocking, AT 4-phase protocol. The ESL IP models are also incorporated with ITRI-patented ESL power analysis interface. The platform can boot Android within minutes, which is hundred times faster than traditional simulation approach. Furthermore, the platform can support detailed IP-level power profiling based on different application scenarios, which provides very useful information for system designer to evaluate, explore, and optimize the system performance and power as earlier as possible.
