GE Intelligent Platforms has announced the daq8580 rugged streaming network appliance, a complete, standalone, application-ready solution that, according to the company, delivers flexibility, high performance and excellent cost-effectiveness. Designed to meet the the growing requirement for unmanned vehicles to capture, process and transmit increasing quantities of video information at increasing resolutions, the daq8580 also extends GE’s growing range of COTS Rugged Systems (CRS) that are designed to provide ready-to-run solutions that minimize both NRE (Non Recurring Engineering) expense and time to market.
The first customer for the daq8580 is the NASA Dryden Flight Research Center (DFRC), working in collaboration with the National Oceanic and Atmospheric Administration (NOAA). The daq8580 will be installed onboard the Northrop Grumman Global Hawk unmanned aerial vehicle, which is being deployed to conduct atmospheric research. The daq8580 video compression platform will ingest high bandwidth, high resolution video streams from Global Hawk’s on-board sensors and compress the data by factors as much as 100:1. The reduced bandwidth video feed can then be transmitted over the communication link to the ground station for observation and analysis with negligible impact on image quality.
The daq8580 is designed for deployment in environments that are constrained in size, weight, and power (SWaP). The new network appliance measures 10.1” long by 7.3” deep, weighs 5 lbs. and consumes 25 watts of power. This is particularly significant for unmanned aerial vehicles (UAVs) where increased weight means increased fuel consumption and reduced mission durations. Similarly, the rugged design of the daq8580 means that it is highly resistant to the shock, vibration and other hostile characteristics typical of deployment in an unmanned vehicle. Its 28V power supply is designed to meet MIL-STD-704E and MIL-STD-1275B, making it suitable for aircraft as well as ground vehicle operations.
The daq8580 can acquire two parallel streams of HD (1,920 x 1,080) at 30 frames/second or up to four channels of standard definition (SD) video. It can also support DVI or VGA modes up to 2,048 X 2,048 pixels. It then processes these streams using an Altera Arria II GX FPGA combined with Texas Instruments media processors. The video streams are encoded to the H.264 industry standard prior to transmission, ensuring the optimum trade-off between image quality and required bandwidth
High-speed ADC devices provide input digitization of the various supported analog video formats. The embedded Altera FPGA controls data capture and routing and can be used for a variety of image processing tasks. The TI DSP co-processors provide efficient and streamlined video data processing. When necessary, the daq8580 can be loaded with custom FPGA and DSP code to perform a broad range of video processing functions on the video input streams.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
