Allocation of scratch-pad memory in priority-based multi-task systems
Hideki Takase, Hiroyuki Tomiyama, Hiroaki Takada · 2009
This paper proposes three approaches for allocation of scratch-pad memory in non-preemptive fixed-priority multi-task systems. These approaches can reduce energy consumption of instruction memory. Each approach is formulated as an integer programming problem which simultaneously determines (1) partitioning of scratch-pad memory spaces for the tasks, and (2) allocation of functions to the scratch-pad memory space for each task. The experimental results show the effectiveness of the proposed approaches.
