Abstract
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.
