Parallel Processing for Multi-core DSPs
Modern video-processing systems run multiple applications such as image processing, compression and content analysis concurrently on many processors. System designers are forced to use multiple DSP chips, FPGAs and a system controller to provide the necessary horsepower. but chip-level software tools don't address the system integration issues.

H.264 Codec: Video Compression for Consumer Applications
As the transition from analog to digital content continues in the AV (audio-visual) world, the number of new consumer devices supporting digital audio and video processing, including TV-sets, and DVD players, continues its rapid climb. As a result, it became one of the most widely adopted compression standard in the consumer space. H.264 is now poised to replace MPEG-2 as the new compression technology with better quality at lower transmission bitrate and storage requirements.

Ada Enhances Embedded-systems Development
Developing an embedded system is hard work. Reliability is essential; indeed, embedded software may control a safety- or security-critical system where an error can have catastrophic consequences. New requirements will almost surely pop up, so the software must be maintain- able. Real-time constraints and memory limitations make time and space predictability and run-time performance important. Many embedded systems comprise activities that are performed concurrently, either with actual parallelism or through multiplexing on a single processor. And most deal at some point with hardware-specific details like interrupt handling and data layout.
