Survey on High Level Synthesis for Image Processing Applications

The term High Level synthesis refers to the generation of register transfer level designs from the user defined behavioral specifications in an automatic manner. The main goal of the HLS is to generate a RTL level design that implements the specified behavior while satisfying the design constraints and optimizing the given cost function. High level synthesis is used in image processing because of its vast advantages in the field of automatic electronic hardware design. The research in HLS on image processing leads to the development of a better image processing results automatically by configuring it with perfect parameters. So, by using HLS for image processing applications lead to new development in this area. Here, present a detailed survey about the recent developments in the HLS on image processing and discussed the recent techniques used in HLS for image processing applications. To locate the further improvement in using high level synthesis in the field of image processing the obstacles in the existing techniques are also discussed. Additionally, the discussion is given about their approaches so that the new development in high level synthesis for image processing is easier for the researchers. Finally, some of the research issue is also addressed to precede the further research on the same direction.
