报告摘要：The rapid development of the Real-Time and Embedded System (RTES) has increased the requirement on the processing capabilities of sensors, mobile phones and smart devices, etc. Meanwhile, energy efficiency techniques are in desperate need as most devices in RTES are battery powered. Following the above two trends, this work explores the memory system energy efficiency for a general multi-core architecture. This architecture integrates a local memory in each processing core, with a large off-chip memory shared among multiple cores. Decisions need to be made on whether tasks will be executed with the shared memory or the local memory to minimize the total energy consumption within real-time constraints. This paper proposes optimal schemes as well as a polynomial-time approximation algorithm with constant ratio.
