In “Versatile stack management for multitasking sensor networks,” Lin Gu in the Department of Computer Science and Engineering, Hong Kong University, with Rui Chu,Yunhao Liu, Mo Li, and Xicheng Lu, evaluate how the use of techniques that combine binary translation and a new kernel runtime can lead to efficient OS designs on resource-constrained platforms supporting preemptive multi-task scheduling, memory isolation, and versatile stack management.
