According to the power model based on algorithm complexity, we analyze the power characteristic on both the algorithm level and micro-architectural level. Therefore, we propose a fusion power model that combines both algorithm level and micro-architectural level. We extract the time complexity and space complexity on the algorithm level, the CPI(Cycles Per Instruction) on the micro-architectural level...
Nowadays as low carbon economy is greatly advocated worldwide, the electricity consumption caused by a huge number of embedded computer systems is gaining more and more attention. Different instruction set, software algorithm and high-level software architecture can significantly affect the system energy consumption. In this paper, we first analyze the relations between software power consumption...
The RTOS (Real-Time Operating System) is a critical component in the SOPC (System-On-Programmable-Chip), in which the hardware-software unified multi-task management and scheduling of RTOS can significantly improve the performance of SOPC. First, we build a unified scheduling policy based on hardware-software unified multi-task management model. Then, we analyze the shared resources competition problem...
