TOP-Down

自顶向下(TOP-Down)的分析算法通过在最左推导中描述出各个步骤来分析记号串输入。将大型的数字电路设计分割成大小不一的小模块来实现特定的功能,最后通过由顶层模块调用子模块来实现整体功能,这就是TOP-Down的设计思想。
  • This paper describes a bus mastering implementation of the PCI Express protocol using a Xilinx FPGA.

    This paper describes a bus mastering implementation of the PCI Express protocol using a Xilinx FPGA. While the theoretical peak performance of PCI Express is quite high, attaining that performance is a complex endeavor on top of an already complex protocol. The implementation is described and its performance is analyzed. Source code is offered for free download via the web.

    When C++ was first introduced many benefits such as code reuse, portability and scalability were promised, but somehow these benefits failed to eventuate. It didn’t take too long before most people in the embedded world decided that the promises were just hype, and settled down to using C++ as a slightly better version of C

    The running time of quicksort can be improved in practice by taking advantage of the fast running time of insertion sort when its input is “nearly” sorted. When quicksort is called on a subarray with fewer than k elements, let it simply return without sorting the subarray. After the top-level call to quicksort returns, run insertion sort on the entire array to finish the sorting process.

    VideoMan (Video Manager) is an open-source C++ library that helps you developing video based applications. We created VideoMan to increase our productivity developing computer vision applications, but it can be used in many other ways. With VideoMan is very easy and fast to initialize any kind of video input like webcams, video files, frame grabbers, IEEE 1394 cameras and so on. You can initialize multiple inputs at the same time and show them in the screen. Also, you can show the results of the processing steps of your computer vision algorithm (extracted edges, back projections, detected blobs...) This way you can see the results of what are you coding, checking the results of your algorithm steps. Moreover, the implemented visualization scheme make easier to combine computer graphics with video, for example to show a 3d model on top of video for augmented reality applications.
