Partitioned fixed priority scheduling is one of the most comprehensively chosen predictable scheduling in practice. The FMLP+ developed in recent years is a better protocol, which ensures asymptotically optimal O(n) maximum priority-inversion blocking. The constraints under several protocols besides the FMLP+ can be exploited to gain the bound on maximum blocking time. However, the blocking time bounds...
A task migration method is proposed for energy savings in multiprocessor real-time systems. The method is based on the portioned scheduling technique which classifies each task into a fixed task or a migratable task. The energy-aware migration with specified parameters is formulated as a linear programming problem, and optimal solution is given. Furthermore, the method is extended to more general...
As the size and complexity of embedded systems are growing, the area cost and performance of the LSI circuits are becoming more crucial. A critical bottleneck for them is interconnections such as multiplexers (MUXs). Thus, a hardware synthesis technique for reducing MUXs, especially during the earlier design phase, has been demanded. This paper presents a novel MUX reduction technique in high-level...
This paper presents a framework for the purpose of energy optimization of embedded real-time systems. We implemented the presented framework as an optimization toolchain and an energy-aware real-time operating system. Our framework is synthetic, that is, multiple techniques optimize the target application together. The main idea of our approach is to utilize a trade-off between energy and performance...
Scratch-pad memory has been employed as a partial or entire replacement for cache memory due to its better energy efficiency. In this paper, we propose scratch-pad memory management techniques for priority-based preemptive multi-task systems. Our techniques are applicable to a real-time environment. The three methods which we propose, i.e., spatial, temporal, and hybrid methods, bring about effective...
