Optimization of Multimedia Codecs using ARM NEON
ثبت نشده
چکیده
Multimedia has become an inevitable part of our daily lives. It finds application in various areas, from education to entertainment. The growth of internet and mobile communication has also increased the use of multimedia applications. Digital audio/video applications for network, wireless-enabled and mobile devices pose a range of constraints such as low channel bandwidth, limited storage capacity and low cost. This has created a need for high quality audio/video at low bitrates.

SAC: An Efficient Retargetable Source-to-Source Compiler for Multimedia Instruction Sets
Multimedia instruction sets allow developments of time and power efficient applications. As a consequence they are widely used in embedded systems, e.g. NEON in ARM processors, but also in general purpose processors e.g. SSEx in Intel and AMD processors and AVX for new processors). Unfortunately, it is difficult to write lowlevel code for such instruction sets, and no portability is possible. S...
متن کاملMolecular mechanics and molecular dynamics analysis of Drexler – Merkle gears and neon pump ∗
Over the past two years at the Materials and Process Simulation Center, we have been developing simulation approaches for studying the molecular nanomachine designs pioneered by Drexler and Merkle. These nanomachine designs, such as planetary gears and neon pump, are described with atomistic details and involve up to 10 000 atoms. With the Dreiding and universal force fields, we have optimized ...
متن کاملSoftware Optimization of Video Codecs on Pentium Processor with MMX Technology
A key enabling technology for the proliferation of multimedia PC’s is the availability of fast video codecs, which are the basic building blocks of many new multimedia applications. Since most industrial video coding standards (e.g., MPEG1, MPEG2, H.261, H.263) only specify the decoder syntax, there are a lot of rooms for optimization in a practical implementation. When considering a specific h...
متن کاملOverlay and Peer-to-Peer Multimedia Multicast with Network-Embedded FEC
Under traditional IP multicast, application-level FEC can only be implemented on an end-to-end basis between the sender and the clients. Emerging overlay and peer-to-peer (p2p) networks open the door for new paradigms of network FEC. The deployment of FEC within these emerging networks has received very little attention (if any). In this paper, we analyze and optimize the impact of Network-Embe...
متن کاملObjective Evaluation of Edge Blur and Ringing Artefacts: Application to JPEG and JPEG 2000 Image Codecs
This paper presents a method of objective evaluation of the edge blur and ringing artefacts produced by image codecs. It is difficult to detect and measure individual artefacts in coded images. A synthetic test image is developed to separate and measure edge blur and ringing artefacts due to image compression. The influence of pixel intensity gradient on the quality metrics is investigated, the...
