CDH SFT Functional Decomposition Grant Fritz

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 Blake Blake Orth

Display Functional Decomposition Blake Orth

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

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

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

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

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

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

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 Blake Orth
