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)
In this paper, we propose, an innovative algorithm for reducing the complexity of the motion estimation (ME) module used in standard video compression applications. The idea is based on applying a motion detection algorithm for the decision of search window sizes in the motion estimation. The motion detection algorithm is based on blob coloring [D.H.… (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)
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)
In this paper, the implementation of a DSP controlled AC-DC matrix converter is presented. Experimental results, obtained with a 5 kW prototype and compared with analogous results of a computer simulated model, are shown. Functional issues are discussed and design solutions proposed and implemented.
