摘要

细粒度(每核)多同步系统需要新的时钟策略和新的体系结构设计技术。本文分别比较了基于双时钟fifo和中同步同步器广泛使用的两种基本多同步实现变体。架构同质的实验设置、同步器与NoC开关缓冲器的成本效益合并、两种架构之间尽可能多的物理合成步骤共享以及真实的全高清视频播放应用的要求是本研究的关键创新。

Contrasting multi-synchronous MPSoC design styles for fine-grained clock domain partitioning: the full-HD video playback case study
Fine-grained (per-core) multi-synchronous systems calls for new clocking strategies and new architecture design techniques. This paper compares two fundamental multi-synchronous implementation variants based on the extensive use of dual-clock FIFOs vs mesochronous synchronizers respectively. The architecture-homogeneous experimental setting, the cost-effective merging of synchronizers with NoC switch buffers, the sharing of as many physical synthesis steps as possible between the two architectures and the requirements of a realistic full-HD video playback application are the key innovations of this study.
