14. Display System Overview
Use DVI for easy interface to screens of various sizes
DVI prioritized over VGA to allow for future expandability
Custom display hardware will allow for a simple embedded solution
Removes the need to interface and power a full rendering graphics card
Current image stored to on-board SRAM for fast access
Will be implemented using TFP410 DVI Trasmitter, Altera MaxII CPLD and 6MB SRAM

16. CPLD Programmed using Verilog through JTAG Clocked at 165MHz
Takes care of all Video memory Operations
Reads pixel data from SRAM chips and presents it at 24-bit DVI chip input
Write new image data to SRAM chips
Receives new image data from the microcontroller via SPI
Manage all SRAM and DVI control lines
Blake Orth

17. EPM570T144C5N Max II – 570 Series 144-TQFP
Selected for fast pin-to-pin propagation delay ( down to 4.5ns)
440 macro-cells allows for reasonably complex logic
Good performance for current draw – at most draws 250mA
Development board being used to develop Verilog code
Blake Orth

18. Display System Hardware
Use TI TFP410 PanelBus DVI Transmitter
Blake
Blake Orth

19. TI TFP410 DVI Transmitter Basic configuration through I2C
Allows settings for resolution, DE generator, and data de-skew
Takes 24-bit True Color pixel data and control signals
Encodes and serializes pixel data to PanelBus DVI and outputs to a standard Single Link DVI Connector
Blake Orth

20. SRAM Stores current image data (1 image) Three SRAM units will be used
24-bit True Color for each pixel
8-bits for each color part (RGB)
Three SRAM units will be used
RGB pixel data stored in parallel
One unit for each color
Shared 20-bit address bus
All parts of a single pixel will have a shared address
Shared 8-bit data bus
Bus control handled with output/write enable pins
Blake Orth

21. SRAM Selection ISSI IS61WV102416 1M x 16b SRAM 8 ns access time
Using 3 modules totals to 6MB of storage
Blake Orth

22. SRAM Modes SRAM has ability for 16-bit data bus
We are using in 8-bit data bus mode
20-bit address selects a 16-bit word
Uses /LB and /UB pins to select upper or lower byte

31. Wifi
Used to update the Display Module with new advertisements & information
Initial Wifly utilizes telnet exclusively
Telnet is completely unsecure
Telnet is Great for sending small strings across local network but not so great at sending large files over internet.
