Parallel Classification of Image Processing Program Based on LLVM Architecture

According to the main characteristics of the image processing algorithm, the conclusion that the image processing algorithm contains a variety of parallel features is analyzed from the model of the mixed structure of the image processing program and the dependencies and parallel features in the program. Then, according to the analysis of the dependencies in the loop, the parallelization of the different levels of the program is found, and the loops are classified. The different categories correspond to the different execution units, and the typical image processing procedures are further analyzed.
