Abstract

This article proposes a hardware/software partitioning method targeted to performance-constrained systems for datapath applications. Exploiting a platform based design, a Timed Petri Net formalism is proposed to represent the mapping of the application onto the platform, allowing to statically extract performance estimations in early phases of the design process and without the need of expensive simulations. The mapping process is generalized in order to allow an automatic exploration of the solution space, that identifies the best performance/area configurations among several application-architecture combinations. The method is evaluated implementing a typical datapath performance constrained system, i.e. a packet processing application.
用于数据路径应用程序的面向性能的硬件/软件分区
本文提出了一种针对数据路径应用程序的性能受限系统的硬件/软件分区方法。利用基于平台的设计,提出了一个定时Petri网形式来表示应用程序到平台的映射,允许在设计过程的早期阶段静态提取性能估计,而不需要昂贵的模拟。映射过程是一般化的,以便允许对解决方案空间进行自动探索,从而在几个应用程序体系结构组合中确定最佳性能/区域配置。该方法在一个典型的数据路径性能受限系统中进行了评估,即数据包处理应用程序。
