Parallel Computing and Optimization Techniques

In recent mobile phones, car navigation systems, digital TVs, and other consumer electronic devices, there is a trend toward digital convergence in which a single device has the ability to process various kinds of applications. At the same time, considering the processing of media content, these devices must be capable of encoding and decoding video images and audio data based on MPEG2, MPEG4, H.264, VC-1, MP3, AAC, WMA, RealAudio, and other formats. Moreover, the latest DVD recorders have the ability to automatically generate digests of video images by using audio and image recognition technology. These kinds of digital convergence devices must be able to flexibly process various kinds of data—media, recognition, data, communications, and so on—and the SoC (System-on-Chip) that is embedded in the devices must deliver superior performance while consuming very small power.
