Abstract: Porting CUDA program to other heterogeneous and many-core architectures by the way of binary translation is significant for extending the range of the CUDA application, leveraging the advantage of many cores and supporting national industry. Begin with the CUDA executive code, a translation framework is designed in which the host-end codes and device-end codes are translated separately based on a method of Divide-and-Conquer. In the course of migration, the solutions of several key problems are described emphatically such as the extraction of device-end codes, the mapping of computing model and storage model, synchronization barrier and instruction translation. The experimental results validate the system’s correctness.
