[Abstract]:Because of the abundant hardware resources and reconfigurable interconnection network, the reconfigurable architecture can provide close to the performance of ASIC and the flexibility of universal processor. Firstly, a domain oriented application customization reconfigurable pipeline architecture is introduced, which can significantly improve computing performance. Secondly, the storage management method for application customization reconfigurable pipeline is introduced. Storage problems are critical to the performance of reconfigurable architectures. This method is based on configuration information dynamic management data input, address calculation and memory access operation separation, can achieve a variety of addressing methods, so that the hardware running on the hardware pipeline efficient flow. Experiments show that compared with the reconfigurable system with special memory access unit, the computational resources are saved and the pipeline efficiency is guaranteed.
