DMAC ISSUE MECHANISM VIA STREAMING ID METHOD |
摘要 |
An apparatus, a method and a computer program are provided for executing Direct Memory Access (DMA) commands. A physical queue is divided into a number of virtual queues by software based on the command type, such as processor to processor, processor to Input/Output (I/0) devices, and processor to external or system memory. Commands are then assigned to a slot based on the type of DMA command: load or store. Once assigned, the commands can be executed by alternating between the slots and by utilizing round robin systems within the slots in order to provide a more efficient manner to execute DMA commands. |
