芯片上的多处理器系统（MPSOC）提供了卓越的性能，同时通过以软件为导向的个性化保持灵活性和可重复性。尽管如今，大多数MPSOC都具有异质性，可更好地满足目标应用程序的要求，但同质MPSOC可能会在不久的将来成为可行的替代方案，带来其他收益，例如运行时负载平衡和任务迁移。本文介绍的工作依赖于我们开发的基于NOC的MPSOC框架，用于探索可扩展和适应性的在线连续映射技术。该系统的每个处理器都是紧凑的，并运行了一个微小的先发制操作系统，该操作系统可监视各种指标，并有权通过代码迁移技术进行重新映射决策。这种赋予架构具有决定性功能的方法允许根据各种标准在运行时提炼应用程序实施。基于简单策略的实验在各种应用上介绍了这种方法的好处。
Multiprocessor Systems-on-Chips (MPSoCs) offer superior performance while maintaining flexibility and reusability thanks to software oriented personalization. While most MPSoCs are today heterogeneous for better meeting the targeted application requirements, homogeneous MPSoCs may become in a near future a viable alternative bringing other benefits such as run-time load balancing and task migration. The work presented in this paper relies on a homogeneous NoC-based MPSoC framework we developed for exploring scalable and adaptive on-line continuous mapping techniques. Each processor of this system is compact and runs a tiny preemptive operating system that monitors various metrics and is entitled to take remapping decisions through code migration techniques. This approach that endows the architecture with decisional capabilities permits refining application implementation at run-time according to various criteria. Experiments based on simple policies are presented on various applications that demonstrate the benefits of such an approach.
