In first place, in this paper, the basic process of parallel code
implementation is discussed for a VLIW architecture. Parallel code modules allow the implementation of a contour active (snake) for segmentation and tracking of endocardium in echocardiographic images. In second place, this work discusses the performance obtained through this design model. In this case, it is necessary to
check performances in order to obtain a qualitative and quantitative
measurement of our implementation. We have chosen one example which permits to understand the methodology used in order to obtain the maximum performance of hardware features of VLIW processor: the distance between points of active contour, very used in different modules composing the active contour algorithm.

In this paper a high-speed procedure for motion tracking of endocardium is presented. If a contour is available in the first frame of a sequence, the contours on the subsequent frames are segmented. Deformable active contours is a technique that combine geometry, physics and approximation theory to solve problems with fundamental important into medical image analysis like segmentation, representation and matching of shapes, and tracking of objects in movement. The procedure was implemented on a DSP processor (TMS320C6701) using its hardware characteristics massively. The results are illustrated on a sequence of four-chambers apical images.
