Bandwidth control for a direct memory access unit within a data processing system |
摘要 |
A method for controlling bandwidth in a direct memory access (DMA) unit of a computer processing system, the method comprising: assigning a DMA job to a selected DMA engine; starting a source timer; and issuing a request to read a next section of data for the DMA job. If a sufficient amount of the data was not obtained, allowing the DMA engine to wait until the source timer reaches a specified value before continuing to read additional data for the DMA job.
