Challenges DRISHTI
Graphics Processing Board (GPB) and its Test setup
The project shall be done in two phases (Phase-1 & Phase-2) Phase-1 : Proof of Concept:To validate the Input/Output Video and Graphics processing capability, Innovator shall develop the Prototype or Engineering Card and prove the following functionality.
• 2D & 3D display page generation.
• Generation and display of graphic, alphanumeric and symbolic data.
• Internally generated graphic symbology information overlaid with external input video.
• External video without overlays.
• Automatic Gain Control (AGC) circuitry in video processing path to compensate for any loss in video signal during transmission to/and receiving from other sources.
• Resizing of raster video received in the desired size and aspect ratio for rendering on display frames and overlay of symbology on it.
• Generation of various display frames of size and display of raster video along with symbology overlaid at the specified location on the display frame and display of other stroke symbology in the remaining area of display frame.
• Display video with Video Pixel format shall be aligned at the centre of display surface as per external command received.
• Display symbol shape shall not be distorted on cropping / scaling function by display i.e. a circle drawn shall not be distorted and get changed to oval shape.
• Display of external video image with overlay of symbols and alphanumeric data.
• Picture In Picture (PIP) display i.e. it shall be possible to resize the external video and place inside internally generated graphics symbology video.
• Generation of snapshot of the displayed page on operator command and transmit the same in compressed/raw image format.
• Read the image snapshot from external LRU’s and display it on the screen based on operator command.
• Maintenance & health monitoring information to the user.
• Antialiasing features to avoid jagged lines/ stair casing effect on video. Innovator shall demonstrate the functionality on Input Video: ARINC-818 Optical (speed upto 4.25 Gbps), ARINC-818 Copper ((speed upto 1.0625 Gbps), RGB STANAG3350B Output Video :ARINC-818 Optical (speed upto 4.25 Gbps), ARINC-818 Copper ((speed upto 1.0625 Gbps), RGB STANAG3350B, LVDS & DVI Phase-2 : Development of Graphics Processing Board(GPB): a) Innovator shall develop MIL-Standard 3U Graphics Processing Board based on Graphics based System on-Chip (SoC) with APIs, Libraries and Drivers compliant to OPEN GL 2.0. Programmable shading for enabling high performance 2D and 3D graphics having following Interfaces:
• ARINC-818 Inputs: i. 2 No’s of Independent Inputs ARINC-818-2 (optical) - (speed upto 4.25 Gbps)ii. 1 No’s of Independent Inputs ARINC-818-2 (copper) - (speed upto 1.0625 Gbps)
• RGB STANAG3350B Inputs: 2 No’s of Independent Inputs
• ARINC-818 Output: 1 No’s of Independent Inputs ARINC-818-2 (optical) - (speed upto 4.25 Gbps) • RGB STANAG3350B Output: 1 No’s of Independent Inputs
• LVDS Output: 1 No of buffered Output (JEDA or VESA configurable)
• DVI Output: 1 No
• XMC Slot: 1 No’s
• JTAG: 1 No’s
• Debug Serial Port: 1 No’s (minimum)
• PCIe Gen3 interface between GPB and other modules b) Innovator shall also develop one Test Jig to test all interfaces of 3U Board. An Acceptance Test Procedure (ATP) shall be prepared by Innovator, which shall be approved by CEMILAC. Innovator shall test the developed board as per approved ATP and to be delivered to HAL as a COTS Module.
