Abstract: The characteristics of 2-D convolutions with big kernel in low-rank are analysed, and a fast algorithm is given. Then a systolic array implementation, which is derived by a three-stage dependence-graph-based mapping approach, is presented. It is shown that the architecture has a high efficiency for parallel processing and a nearly linear speed-up. -
