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.

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
