The IDK contains a oating point C6711 DSP, and other hardware that enables real time video processing. In addition to the IDK, the video processing lab bench is equipped with an NTSC camera and a standard color computer monitor. You will complete an introductory exercise to gain familiarity with the IDK programming environment. In the exercise, you will modify a C skeleton to horizontally ip and invert video input from the camera. The output of your video processing algorithm will appear in the top right quadrant of the monitor. In addition, you will analyze existing C code that implements ltering and edge detection algorithms to gain insight into IDK programming methods. The output of these "canned" algorithms, along with the unprocessed input, appears in the other quadrants of the monitor. An additional goal of this lab is to give you the opportunity to discover tools for developing an original project using the IDK. 2 Video Processing Setup The camera on the video processing lab bench generates an analog video signal in NTSC format. NTSC is a standard for transmitting and displaying video that is used in television. The signal from the camera is connected to the "composite input" on the IDK board (the yellow plug). This is illustrated in Figure 2-1 on page 2-3 of the IDK User's Guide [ ? ]. Notice that the IDK board is actually two boards stacked on top of each other. The bottom board contains the C6711 DSP, where your image processing algorithms will run. The top board is the daughterboard, which contains hardware for interfacing with the camera input and monitor output. For future video processing projects, you may connect a video input other than the camera, such as the output from a DVD player. The output signal from the IDK is in RGB format, so that it may be displayed on a computer monitor. At this point, a description of the essential terminology of the IDK environment is in order. The video input is rst decoded and then sent to the FPGA, which resides on the daughterboard. The FPGA is responsible for the lling of the frame bu er and video capture. For a detailed description the FPGA and its functionality, we advise you to read Chapter 2 of the IDK User's Guide [ ? ]. The Chip Support Library ( CSL ) is an abstraction layer that allows the IDK daughterboard to be used with the entire family of TI C6000 DSPs (not just the C6711 that we're using); it takes care of what is di erent from chip to chip....
