This document discusses challenges in developing embedded systems for wireless radio technologies. It describes the engineering and technology challenges, including needing to support field upgrades, comprehensive testing, delayed hardware availability, and stringent development schedules while keeping costs and power consumption low. It also outlines some common hardware platforms used for wireless radio, including ASICs, DSPs, FPGAs, and software-defined radios. The document then provides two case studies on developing a 3G protocol conformance tester and an IEEE 802.16 WiMAX MAC system to demonstrate challenges and solutions.

MIPI DevCon 2016: How to Use the VESA Display Stream Compression (DSC) Standa...MIPI Alliance
The VESA Display Stream Compression (DSC) standard is a visually lossless video compression algorithm that decreases transmission bandwidth by up to 3X, while lowering power and reducing EMI. The standard has been adopted by leading suppliers of semiconductors for use in mobiles, tablets, in-car video, and DTV applications in order to achieve higher resolution displays. This presentation by Hardent's Alain Legault provides background information about DSC and the role it plays in today’s interface IP ecosystem when combined with MIPI® DSI, USB Type-C™, DisplayPort™ and Embedded DisplayPort™, and HDMI™ IPs. Several use cases are discussed, and practical information on how to successfully integrate DSC in semiconductor designs is also provided.

OpenDataPlane (ODP, https://www.opendataplane.org) является open-source-разработкой API для сетевых data plane-приложений, представляющий абстракцию между сетевым чипом и приложением. Сейчас вендоры, такие как TI, Freescale, Cavium, выпускают SDK с поддержкой ODP на своих микросхемах SoC. Если проводить аналогию с графическим стеком, то ODP можно сравнить с OpenGL API, но только в области сетевого программирования.

implemented in hardware (at least for portable devices)
Yet needs to meet real-time constraints
Yet has to be developed under stringent development schedule
Yet needs to follow laws of Physics
5. 5
Technology Challenges
Standard-driven – hence development has to start before standard is
out and needs to adapt to standard modifications

standard adaptation
Technology life is usually small – need to extend this through partners
and industry bodies
Yet has to be of lower cost
Yet has to be of lower power (at least for portable devices)
