The increase in the availability of bandwidth for wireless links, network integration, and the computational power on fixed and mobile platforms at affordable costs allows nowadays for the handling of audio and video data, their quality making them suitable for medical application. These information streams can support both continuous monitoring and(More)
This paper proposes a design approach based on integrated architectural and system-on-chip (SoC) simulations. The main idea is to have an efficient framework for the design and the evaluation of multimedia terminals, allowing a fast system simulation with a definable degree of accuracy. The design approach includes the simulation of very long instruction(More)
Today there are new high band requests from actual multimedia services, and efficient video coders are needed in order to obtain a sensible reduction of video streams band occupation, maintaining video quality. The new video coding standard H.264 seems to be answer to fulfill these requirements. On the other hand, the H.264 encoder complexity is largely(More)
In this paper, a system-on-chip design and simulation of an Audio-Video encoding terminal has been described. The purpose of this work was to model a multimedia mobile terminal in order to preliminarily explore system bottlenecks and inter device communications. The system is based on two ST210[1] processors working in parallel, one dedicated to the(More)
Recent advances in embedded computer electronics and integration in multimedia standard specifications are enabling cost-effective terminals for video communication and conferencing with potential capabilities in video surveillance application, both on wireless and wired links. Following a tutorial approach, the paper describes the practical implementation(More)
