An image processing library for C-based high-level synthesis

Abstract

We introduce a library for the productive development of image processing accelerators using C-based high-level synthesis. The key concept of our approach is to provide a set of generic building blocks that is applicable to a multitude of image processing applications. An efficient memory architecture that facilitates easy integration of point and local image processing operators is the centerpiece of the library. The generic building blocks are kept very compact and can be tailored to support sophisticated processing techniques. The representation enables the designer to comply with specific design requirements, such as stringent timing constraints or limited resource budgets. Results show a significant gain in productivity compared to hand coded implementation while delivering comparable performance and resource requirements.
