The TMS320C64x image/video processing library (IMGLIB) provides a set of C-callable,assembly-optimized functions commonly used in imaging applications. While IMGLIB can be used to develop practical real-time applications with its high performance and ease of use,there are several important factors to consider in a system environment for attaining optimal performance mainly due to the data-intensive nature of imaging applications. This application report presents the usage and performance of several IMGLIB functions to help users utilize IMGLIB in their system development, and also presents performance analysis with three kinds of memory scenarios to help understand potential overhead related to memory hierarchy.……
