On Multi-Task Scheduling for Reducing Heap Memory Consumption Using Live Variable Analysis
Hiroki Funase, Akio Nakata (Hiroshima City Univ.) SS2012-2
Abstract (in Japanese) (See Japanese page) 
(in English) Multitasking system often consume more memory than singletasking system, because when context switching occurs, the running task stops executing while preserving its working memory. Although such memory consumption can be reduced by sharing the working memory that is not used by multiple tasks at the same time, it is challenging to analyse statically which memory can be used at the same time by multiple tasks, especially for heap memory that is allocated dynamically during task execution. In this paper, we consider a scheduling technique to reduce heap memory consumption of multitasking systems which consists of mutually independent tasks with no branches nor loops by using the information of the time sequence of heap memory usage extracted by live variable analysis.
