Abstract

We present DG2VHDL, a design tool which can automatically translate abstract algorithmic descriptions, known as Dependence Graphs, to synthesizable VHDL models and testbenches representative of distributed memory and controlprocessor arrays, known as Signal Flow Graphs. This translation facilitates the rapid exploration of the large space of available parallel architectures for a given problem and frees the designer from having to code and testseparately, using a Hardware Description Language, every candidate architecture under consideration. It is shown that the quality and scalability of the automatically generated VHDL models is near optimal, in the sense that the time required to synthesize them as well as the area of the resulting hardware grows at the lowest possible rate with the problem size. This makespossible the high level synthesis of processor arrays for large size real world problems, such as the computation of the Discrete Wavelet Transform and the estimation of Higher Order Statistics, that are presented as case studies.
