November 11, 2015, ARM TechCon, Santa Clara, CA–Mike Assenti from Dolby Laboratories talked about the energy consumed in audio processing tasks. He provided definitions and basic techniques for taking power measurements in smaller devices. The growing number of apps for audio functions in mobile devices is a clear indicator of user desire for better audio. [...]

November 11. 2015, ARM Techcon, Santa Clara,CA—Cole Li from DSP Concepts presented information on advanced microphone processing on ARM processors. The growing number of devices that include microphones requires better understanding of mike characteristics and how to process their signals. Mikes are not only in phones and tablets, but are moving into automotive and IoT [...]

August 20, 2015, Intel Developer Forum, San Francisco—Rik Dunphy from Intel presented some tips for optimizing video processing and delivery on Xeon processors. The latest E3 processor family has added new processing capabilities which will require different approaches to server-class video processing. The nature of video workloads is changing with more offline file-based transcoding, and [...]

June 16, 2015, SMPTE Entertainment Technology in the Internet Age, Stanford, CA—Lars Borg from Adobe describes some of the differences between standard dynamic range and high dynamic range workflows. These new specifications calling for wider color gamut and higher dynamic range will impact content workflows. Current HD TV is based on BT 709 to provide [...]

June 3, 2015, Society for Information Display Symposium, San Jose, CA –Kathrin Berkner from Ricoh Innovations talked about the advances in light-filed imaging and the basic principles for designing a light-field system. The challenges for an end-to-end system are in managing the data volumes and computational tasks. Among the techniques for capture, plenoptic cameras are [...]

June 2, 2015, Society for Information Display Symposium, San Jose, CA—Robert Li Kam Wa from Rice University talked about rethinking the imaging pipeline for energy-efficient, privacy-preserving continuous mobile vision. The always-on world has been adding more and higher resolution imaging capabilities, so the industry has to consider how to protect the information. The primary changes [...]

February 23, 2015, ISSCC, San Francisco—Sehat Sutardja from Marvell Semiconductor noted that SoC designs are getting too complicated due to the freezing of the underlying computer architectures.
