H.263 video encoder implementation on a scalable DSP system

A mapping and realization of H.263 video encoder for video conferencing applications are given using our DSP based multiprocessor system, called PAKNEU. PARNEU system is built for computationally intensive applications like image and video processing as well as soft computing applications. PARNEU has flexible communication architecture and thus it allows different mapping possibilities. The presented data parallel mapping has low communication and memory requirements, which allows encoding of any of the five standard H.263 picture formats. With a prototype system using four ADSP-21062 DSPs, a real-time encoding is achieved with QCIF sized picture. Phase times for each step of H.263 encoder are presented.
