This paper considers the automatic synthesis of systolic architectures from nested loop algorithmic specifications. The high level i nput i s given in the form of uniform dependence loops with un it dependencies and the target architecture is a multidimensional systolic array with unbound ed nu mber of cells. A complete methodology for the hardware synthesis of t he resulting a rchitecture, based on VHDL specifications, is presented. This methodology automatically detects all necessary c omputation and communication elements and produces optimal l ayouts. The theoretical f ramework of our method is based on the properties of t he generalized UET grids. First, we c alculate the optimal makespan for the generalized UET grids and then we establish the minimum number of systolic cells required to achieve the optimal makespan. The c omplexity of t he proposed scheduling a lgorithm is completely independent of the size of the nested loop and depends only on its dimension, thus being the most efficient (in terms of complexity) known to u s. All t hese methods were implemented and incorporated in an integrated software package which provides the designer with a powerful parallel design environment, from high level algorithmic specifications to low- level (i.e., actual layouts) optimal implementation. |
