Abstract

An electronic apparatus has a processor; a peripheral having a data interface and a data-attribute interface; a direct memory access (DMA) controller for the peripheral; a memory; a bus system connecting the processor, the DMA controller, and the memory; a data link between the DMA controller and the peripheral; and a data-attribute link between the DMA controller and the peripheral, separate from the data link. The DMA controller has data-transfer circuitry for transferring data between the memory and the data interface of the peripheral over the data link, and for transferring data-attribute information, associated with the data, between the memory and the data-attribute interface of the peripheral over the data-attribute link.
