Description
This paper presents pipeline vectorization, a method for synthesizing hardware pipelines in reconfigurable systems based on software vectorizing compilers. The method improves efficiency and ease of development of reconfigurable designs, particularly for users with little electronics design experience. We propose several loop transformations to customize pipelines to meet hardware resource constraints, while maximising available parallelism. For ran-time reconfigurable systems, we apply hardware specialization to increase circuit utilization. Our approach is especially effective for highly repetitive computations in DSP and multimedia applications. Case studies using FPGA-based platforms are presented to demonstrate the benefits of our approach and to evaluate trade-offs between alternative implementations. The loop tiling transformation, for instance, has been found to improve performance by 30 to 40 times …
