A Scratch-Pad Memory Management Framework for Embedded Real-Time Systems

摘要

In this paper, we propose a scrath-pad memory (SPM) management framework for minimizing energy consumption in preemptive fixed-priority multi-task real-time systems. The framework achieves energy minimization in the instruction memory subsystems. At the design time, energy-optimal usage of SPM, i.e., SPM partitioning and code allocation, is determined. At runtime, SPM is managed with the cooperative support of a real-time operating system and hardware modules. The proposed framework has been implemented in our simulation environment, show the results of effectiveness of the proposed framework, and its effectiveness has been demonstrated by a set of experiments.
