Developed as an industry-wide compression standard for video interfaces, offering visually lossless performance and low latency, the DSC has been adopted into VESAs embedded DisplayPort (eDP) v1.4 and into MIPI Display Serial Interface (DSI) Specification v1.2, which are used for embedded display interfaces within mobile systems, including smartphones, tablets and laptops. Increasing display resolution and higher refresh rates present challenges for small-display mobile devices and laptops, as well as large external displays. As display resolutions increase, the interface payload capacity must increase either with more powerconsuming bandwidth, video data compression, or both. Displays going beyond 4K resolutions will push the video data rate beyond the current limits of the interface standards. For example, standard 1080p displays require a video data rate of 3.5 gigabits/sec; 4K displays at 60Hz require 14 Gb/s; and future 8K displays will require over 50 Gb/s. On-going development of DisplayPort standards, which includes 8K resolution support, foresaw the need for compression because of inherent limits in the existing display interface cables. VESAs DSC standard version 1.0 enables up to 66 percent data rate reduction, extending battery life in mobile systems and laptops, while simplifying the electrical interface requirements for future 4K and 8K displays. The standard enables a single codec for system chips that have multiple interfaces. The VESA DSC Task Group, in collaboration with the MIPI Alliance Display Working Group, co-defined requirements for a high quality compression specification that meets the needs of todays varied display usage, which includes a wide range of image types from still graphics and text overlaps, to photography and video. Video Electronics Standards Association (VESA) www.vesa.org Artesyn opens ATCA management framework to third parties to slash integration time Artesyn Embedded Technologies has developed a new software framework for its ATCA systems that can cut develop time by 40 percent by allowing third party applications. The System Services Framework (SSF) is a complete system management suite for Artesyn ATCA systems that is also open to third party application. It allows users or applications to configure and monitor the hardware and software elements of a single ATCA shelf or across multiple shelves. A graphical user interface provides a quick and easy view of system configuration, events and alarms as well as providing a means of configuring switches or payload blades and managing system access. Artesyn’s SSF also provides XML and command line interfaces so user applications have access to the system parameters and controls. The SSF can be enhanced with Artesyn and 3rd party add-on software modules. For example, Artesyn’s ViewCheck provides in-service and out-of-service diagnostics of ATCA blades and other system elements. Another addin, Artesyn’s FlowPilot, provides a complete packet load balancing solution. “By using Artesyn’s System Services Framework and its add-in software modules, our customers can focus on their value-add application. We estimate it can save customers up to 40 percent time-to-market versus writing or porting their own system management software”, said Jim Darroch, director of software marketing, Artesyn Embedded Technologies, which was formerly Emerson Network Power’s Embedded Computing & Power business. “Artesyn SSF provides the tools necessary to speed the development process and brings a whole new level of ease-of-operation to ATCA systems.” Artesyn Embedded Technologies www.artesyn.com www.electronics-eetimes.com Electronic Engineering Times Europe May 2014 41
