IMEC speeds up scalable video decoder (SVC) with factor 20

15.01.2008
IMEC has further improved its source-code for standard-compliant Scalable Video Decoding (SVC = H.264 extension), now performing 20 times faster and using only a tenth of the memory footprint compared to the SVC standard reference code.

These groundbreaking results were obtained by further optimizing the code mainly through the removal of redundant code and function calls as well as through the improved memory use of IMEC’s earlier (mid 2007) SVC source code. This code was already two times faster than the reference code.

The first optimization was based on (re)structuring the SVC code into more concise functional blocks. This facilitated extra optimizations, including removing redundant code and function calls. The application of DTSE (Data Transfer and Storage Exploration) transformations enabled intelligent (re)use of the memory footprint. As a result of the increased data locality, the total memory footprint was significantly reduced to one tenth, leading to much better cache behavior and higher performance. This will also contribute to reducing the silicon cost area when using SVC functions for ASIC (application-specific integrated circuit) implementations.

The optimized decoder has been benchmarked against the reference decoder on a normal end user PC platform. Compliancy to the SVC standard was also verified. The configurations that were tested included the three scalability types of SVC, being spatial, temporal and quality scalability. The preliminary performance evaluation shows that IMEC’s decoder is up to 20 times faster than the reference software, while consuming only a tenth of the memory.

The optimized source code is available as starting point for product development by industry via a licensing program and can be delivered as source code. The code is of typical interest for system integrators of mobile devices or telecommunication applications and fabless IC makers to help them extend their multimedia reference platforms to comply with the SVC standard.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
