REGULAR ARRAY SYNTHESIS FOR IMAGE AND VIDEO APPLICATIONS

Many design methods have been proposed to synthesize RAAs. The majority of these methods (see chapter 1 for an overview) are based on an affine transformation (first described by Quinton [15] and Moldovan [12]) to map the index space of the application description to time and processor space. The use of such a transformation method simplifies the design task considerably and requires only a few parameters to characterize a design completely. Unfortunately, most of these methods start from a relatively low level specification, using sets of UREs (uniform recurrence equations) [3] or CUREs (conditional uniform recurrence equations) [17] to describe an application. Moreover, especially in the case of real-time signal processing applications, the resulting architecture is usually unnecessarily fast or too slow. 

Therefore, we propose a novel design script to design RAAs for real-time applications. This script is described in section 2. The different steps of the design script are detailed in sections 4 through 7. The methods of the different steps are illustrated by applying them on a real-life application which is described in section 3.
