ABSTRACT:
Various embodiments of a system and method for configuring a set of DMA resources as multiple virtual DMA channels are disclosed. In one embodiment, a system may include a context memory configured to store context parameters for each of the virtual DMA channels, a set of DMA resources, a DMA controller coupled to the context memory, and several I/O resources. The DMA controller is configured to configure the set of DMA resources as different virtual DMA channels using context parameters associated with different respective ones of the virtual DMA channels. Each virtual DMA channel corresponds to one of the I/O resources.
