Abstract

This proposes a method and apparatus for DMA transfer broadcast across multiple interfaces and multiple paper address ranges to improve DMA performance for graphics applications like image processing. The important components of this idea are: a system having multiple interfaces partitioned across different address ranges, a DMA controller to transfer data among all interfaces and an application like graphics which requires good data broadcast performance
