Library-based Mapping of Application to Reconfigurable Array Architecture

Abstract—Reconfigurable array architecture is recently attracting much attention. It is a flexible hardware architecture, which can dynamically change its confi-guration to execute various functions while maintain-ning high performance. However, pursuing flexibility and performance at the same time leads to complexity, thereby makes the mapping of applications a difficult process. There have been attempts to use compiler or high level synthesis techniques to solve the problem. In this paper, we propose yet another method, which uses libraries for the mapping to provide an abstract-tion of the internal structure and at the same time to reduce the development time and efforts through the automated process. We have selected a JPEG decoder as an example to apply the proposed method. As a result, we obtained about 20 % less performance compared to manual mapping but development time is dramatically reduced to less than 1%.
