Real-Time Implementation of a New Contour Tracking Procedure in a Multi-Processor DSP System

چکیده
In this paper the implementation of a contour tracking procedure is presented. If a rough contour of the desired structure is available on the first frame of a sequence, the contours on the subsequent frames are automatically outlined in real time. Furthermore, indices of clinical interest are calculated from the computed contour and they are graphically displayed in real time. The software runs in an integrated software/hardware environment based on the interaction of a PC and a multi-processor DSP (TMS320C80). The paper describes the solutions adopted in order to obtain an efficient software implementation. The performance of the system was investigated and a comparison with a PC implementation is reported. The system was tested by monitoring the area changes of the thoracic aorta in sequences of echographic images. Key-Words: real-time, contour tracking, DSP, medical imaging, multi-processor.

Settling time is one of the most important parameter in design of DLLs. In this paper we propose a new high speed with low settling time Delay Locked Loop (DLL) in which a digital signal processor (DSP) is used instead of using phase-frequency detector, charge pump and loop filter in conventional DLL. To have better settling time, PRP conjugate gradient algorithm is used to optimize delay of ea...
