As semiconductor technology has advanced, many storage systems have begun to use non-volatile memories as storage media. The organization and architecture of storage controllers have become more complex to meet various design requirements in terms of performance, response time, quality of service (QoS), and so on. In addition, due to the evolution of memory technology and the emergence of new applications, storage controllers employ new firmware algorithms and hardware modules. When designing storage controllers, engineers often evaluate the performance impact of using new software and hardware components using software simulators. However, this technique often yields limited evaluation accuracy because of the difficulty of modeling complex operations of components and the interactions among them. In this article, we present a reconfigurable flash storage controller design that serves as a rapid prototype. This design can be synthesized into a field-programmable gate array device and used in a realistic performance evaluation environment. We show the usefulness of our design by demonstrating the performance impact of design parameters.

随着半导体技术的进步，许多存储系统已经开始使用非易失性存储器作为存储介质。存储控制器的组织和架构变得更加复杂，以满足在性能、响应时间、服务质量 (QoS) 等方面的各种设计要求。此外，由于内存技术的发展和新应用的出现，存储控制器采用了新的固件算法和硬件模块。在设计存储控制器时，工程师经常使用软件模拟器评估使用新软件和硬件组件对性能的影响。然而，由于难以对组件的复杂操作和它们之间的交互进行建模，这种技术通常会产生有限的评估准确性。在本文中，我们提出了一种可重新配置的闪存存储控制器设计，可用作快速原型。该设计可以合成为现场可编程门阵列器件，并用于真实的性能评估环境。我们通过展示设计参数对性能的影响来展示我们设计的实用性。
