Bouncing Ball.Organization and GradingFlexibility in the Second Part of the Semester• You can work on all lab assignments from Part II of the course either individually or in groups of two students. • The number of required and bonus tasks, as well as the grading scheme will be different for individuals and the groups of two.• In case of the group work, both students are expected to be intimately familiar with the entire solution to the given lab assignment and the entire lab report. This knowledge will be verified during the experiment demonstration and the same grade will be applied to the entire team.Flexibility in the Second Part of the SemesterLab 4: VGA display (2 weeks) – 6 pointsLab 5: DSP & FPGA Embedded Resources (2 weeks) – 6 pointsLab 6: PicoBlaze & Serial Communication (3 weeks) – 6 pointsLab 6a: Logic Analyzer (in class) – 2 pointsLab 4: VGA display (3 weeks) – 6 pointsLab 5: DSP & FPGA Embedded Resources (4 weeks) – 6 pointsLab 6a: Logic Analyzer (in class) – 2 pointsSchedule A: Schedule B: Total: 20 pointsTotal: 14 pointsVGA BackgroundVideo Graphic Array (VGA)•Resolution: 640x480•Display: 16 colors (4 bits), 256 colors (8 bits)•Refresh Rate: 25Hz, 30Hz, 60Hz (frames / second)•RGB: Red, Green and Blue colorsHorizontal TraceHorizontal FlybackVertical Flyback06394790VGA MonitorVGA Control Signal TimingResolution640x48032 us30.08 us26.24 us25.6 us32 us30.08 us26.24 us32 us30.08 us15.36 ms15.68 ms16.8ms15.744 msVGA Control Signal TimingResolution640x48032 us30.08 us26.24 us640 clock cycles32 us30.08 us656 clock cycles800 clock cycles752 clock cycles480 lines490 lines525 lines492 linesFrequency 25MhzVGA 15 PinPINs on BoardNET "HS" LOC = "J14" | DRIVE = 2 | PULLUP ; NET "VS" LOC = "K13" | DRIVE = 2 | PULLUP ;NET "OutRed<2>" LOC = "F13" | DRIVE = 2 | PULLUPNET "OutRed<1>" LOC = "D13" | DRIVE = 2 | PULLUP ; NET "OutRed<0>" LOC = "C14" | DRIVE = 2 | PULLUP ; We do not use this pin.
