QUKU: A fast run time reconfigurable platform for image edge detection

Abstract

To fill the gap between increasing demand for reconfigurability and performance efficiency, CGRAs are seen to be an emerging platform. In this paper, a new architecture, QUKU, is described which uses a coarse-grained reconfigurable PE array (CGRA) overlaid on an FPGA. The low-speed reconfigurability of the FPGA is used to optimize the CGRA for different applications, whilst the high-speed CGRA reconfiguration is used within an application for operator re-use. We will demonstrate the dynamic reconfigurability of QUKU by porting Sobel and Laplacian kernel for edge detection in an image frame. © Springer-Verlag Berlin Heidelberg 2006.
