Reconfigurable computing is intended to fill in the gap between hardware and software, potentially achieving a much higher performance than software, while maintaining a higher level of flexibility than hardware. By placing the computational-intense portions of an application onto the reconfigurable hardware, it will accelerate the system performance greatly. The implementations of cryptography services for IT (Information Technology) security on wireless devices and embedded systems present a great challenge, particularly to the memory, power, computation resources, and mobility constraints. Reconfigurable computing can serve as an excellent platform for hybrid cryptosystems on restricted computing environments and wireless devices. The reconfigurable architectures increase the flexibility of system schemes and the efficiency of computation resources, and reduce the total cost.  Moreover, hardware piracy issues cause  huge  profit loss in the  IT industry.  In this research project, we also examine how to use the reconfigurable computing/architecture to protect the hardware IP (Intellectual Property).  Image processing plays a crucial role in areas of medicine, crime prevention and investigation, publishing, entertainment, education, and scientific research.  It has become urgent to find the desired images from an image database quickly and automatically. This technique is known as content-based image retrieval (CBIR). However, little research has been done to use the reconfigurable computing technique to speed-up the image retrieval. We will explore new approaches of image retrieval and propose efficient algorithms and fast implementation to improve the retrieval rate of current CBIR systems. My research goal is to investigate and design reconfigurable architectures with low costs, high speeds, and high flexible structures to support real-time online secure data communications, hardware IP (Intellectual Property) protection, and image retrieval. The proposed reconfigurable architectures have regular structures and are very suitable for high speed VLSI implementation.  The academic and technical achievements of this research program can be applied to many areas including but not limited to cable network services, electronic commerce, wireless network and devices, remote system access, smart cards, medical records, hardware privacy prevention, crime investigations, while providing high flexible scheme within the applications.

可重新配置的计算旨在填补硬件和软件之间的空白，可能比软件更高的性能，同时保持比硬件更高的灵活性。通过将应用程序的计算强度部分放置在可重构硬件上，它将大大加速系统性能。无线设备和嵌入式系统上的加密服务（信息技术）安全性的实现带来了巨大的挑战，可重新配置的计算可以作为在限制的计算环境和无线设备上混合密码系统的绝佳平台。可重构体系结构提高了系统方案的灵活性和计算资源的效率，并降低了总成本。此外，硬件盗版问题在IT行业造成了巨大的利润损失。在此研究项目中，我们还研究了如何使用可重构计算/体系结构来保护硬件IP（Intelectual属性）。图像处理在医学，预防犯罪和投资，出版，娱乐，教育和科学研究领域中起着至关重要的作用。快速自动自动从图像数据库中找到所需的图像已经很紧迫。该技术称为基于内容的图像检索（CBIR）。但是，几乎没有研究使用可重构计算技术来加快图像检索。我们将探讨图像检索和提案有效算法和快速实施的新方法，以提高当前CBIR系统的检索速率。我的研究目标是以低成本，高速和高灵活的结构进行调查和设计可重构体系结构，以支持实时在线安全数据通信，硬件IP（知识产权）保护和图像检索。提议的可重构体系结构具有规则的结构，非常适合高速VLSI实施。该研究计划的学术和技术成就可以应用于许多领域，包括但不限于有线电视网络服务，电子商务，无线网络和设备，远程系统访问，智能卡，医疗记录，预防硬件隐私，犯罪调查，同时在应用程序中提供高灵活的计划。
