Architecture exploration is the problem of searching the design space of a given application to find a near optimal or sub-optimal solution in the form of a hardware implementation. The application is normally described using a software model and the main objectives of the exploration tool are to construct an efficient architecture and map the software model to the proposed hardware. Reconfigurable computing (RC) is becoming increasingly popular as it bears the promise of combining the flexibility of software with the performance of hardware. The runtime reconfiguration environment provides common benefits in adapting hardware algorithms during system runtime, sharing hardware resources to reduce device count and power consumption, shortening reconfiguration time e.t.c. Many promising application domains for reconfigurable embedded systems combine high performance demands with frequent changes of their workloads. Examples for such application domains are found in wearable computing, mobile systems, vision tracking and network processors. The emergence of partial dynamic reconfiguration has added new dimensions to the reconfigurable computing, however, at the same time it has added new set of challenges to the designers in evaluating the performance of such systems.

架构探索是搜索给定应用程序的设计空间以找到硬件实现形式的接近最优或次优解决方案的问题。应用程序通常使用软件模型进行描述，探索工具的主要目标是构建一个有效的体系结构，并将软件模型映射到建议的硬件。可重构计算（Reconfigurable Computing，RC）因其兼具软件的灵活性和硬件的高性能而受到越来越多的关注。运行时重配置环境提供了在系统运行时期间适配硬件算法、共享硬件资源以减少设备数量和功耗、缩短重配置时间等方面的共同益处。可重构嵌入式系统联合收割机的许多应用领域结合了高性能要求和工作负载的频繁变化。这样的应用领域的示例在可穿戴计算、移动的系统、视觉跟踪和网络处理器中找到。部分动态重构的出现为可重构计算增加了新的维度，但同时也给设计者评估此类系统的性能带来了新的挑战。
