| description | A method, an apparatus, and a computer program are provided for controlling memory access. Direct Memory Access (DMA) units have become commonplace in a number of bus architectures. However, managing limited system resources has become a challenge with multiple DMA units. In order to mange the multitude of commands generated and preserve dependencies, embedded flags in commands or a barrier command are used. These operations then can control the order in which commands are executed so as to preserve dependencies. |
