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.
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.
The STi7141 is a highly integrated SoC (systemon-
chip) designed to meet the demanding needs of
the interactive cable set Top box market place. The
STi7141 integrates all the major system functions
into a single device, and provides world leading,
multi-layer, advanced security technologies to
protect valuable video and audio assets.
