Array OL specification model is a mixed graphical-textual language designed to model multidimensional intensive signal processing applications.Data and task parallelism are specified directly in the model. High level transformations are defined on this model, allowing the refactoring of an application and furthermore providing directions for optimization. The resemblances between with the wide-known and used Loop transformations lead us to try taking concepts and results from this domain and see how they fit in Array OL context.
