are considered fractional . The range s of values are : Y = 16 to 235 or 040h to 3ACh (i.e. 220 values) Cr = 16 to 240 or 040h to 3C0h (i.e. 225 values) Cb = 16 to 240 or 040h to 3C0h (i.e. 225 values) Prior to any computations, the inputs (Y, Cr and Cb) should be bounded within the valid range (i.e. when Y = 3CCh, it must be replaced with 3AC h). If any of the inputs are outside of the valid range, it should be changed to the nearest value within the valid range before any computations.

The values of R, G and B should change on the falling edge of the clock signal. The reset signal will set all R, G and B to all 0 s on the falling edge of the clock (synchronous reset). You may use any operation or construct you know in VHDL to describe a synthesizable hardware for your design. You do not need to use your 16 bit ALU for the arithmetic operations, and it is not recommended. Suggestions on how to use the multiplication operator in VHDL can be found in the XST user guide under HDL coding techniques. There is a subsection titled Arithmetic Operations. Laboratory Exercise : Please generate comprehensive test cases to verify the functionality of your design. You will need to demo your circuit to your TA, using any test values your TA desires. You will be using ModelSim to simulate and test your design. Also you are required to do comprehensive research on ITU -R BT.656 and ITU-R BT.601 standards along with NTSC, SVGA and their timing reference signals (TRS). You will be using these video standards extensively in the next couple of labs. Therefore you must get familiar with their functionality . Please write a short summary (at least one page) on the standards along with their timing signals. Internet might be a good re source for this research. Final Report You are required to submit a written report summarizing what you have accomplished in this project. Only one report is required per group, so don t forget to include the names of all team members (but only on the first page.) Your report should be a SINGLE Microsoft Word document file and should include the following: Project background and specification Design approach and challenges Implementation details ( S chematics, VHDL ) Size of your design (slice count) Simulation results (waveforms) References, if any.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
