FAST HADAMARD TRANSFORM VERILOG FOR IMAGE PROCESSING

本设计主要用来进行图像采集处理，通过摄像头采集图像信息，经过插值算法后存储到外部SDRAM，然后读取图像数据，进行边缘滤波处理后经VGA输出到屏幕上。(This design is mainly used for image acquisition and processing,through the camera capture image information,after interpolation to the external memory after the SDRAM,and then read the image data processed by the edge filter VGA output to the screen.)

本程序给出了在FPGA板上实现LCD显示的方法。支持的FPGA有APARTAN 3、SPARTAN 3E、VIRTEX 3等

The use of FPGAs for cryptographic applications is highly attractive for a variety of reasons but at the same time there are many open issues related to the general security of FPGAs. This contribution attempts to provide a state-of-the-art description of this topic. First, the advantages of reconfigurable hardware for cryptographic applications are discussed from a systems perspective. Second, potential security problems of FPGAs are described in detail, followed by a proposal of a some countermeasure. Third, a list of open research problems is provided. Even though there have been many contributions dealing with the algorithmic aspects of cryptographic schemes implemented on FPGAs, this contribution appears to be the first comprehensive treatment of system and security aspects.
