Abstract:
A method of real-time data acquisition in a processing component using chained direct memory access (DMA) channels includes receiving a DMA event signal in a DMA controller of the processing component, and executing, responsive to the DMA event signal, DMAs to read at least one data sample from a peripheral device. A last DMA performs a write operation to acknowledge completion of the DMA event.

Claim (Index 1):
A method comprising:\n in a direct memory access (DMA) controller of a processing component, receiving a fixed rate series of data ready signals from a peripheral device, including at least first and second data ready signals; generating a first DMA event signal responsive to the first data ready signal; responsive to the first DMA event signal, executing a first set of DMAs to: read and store at least one first data sample from the peripheral device without interrupting the processing component and without software intervention; and read a synchronization signal; after completion of reading from the peripheral device by the first set of DMAs, generating a second DMA event signal responsive to the second data ready signal; responsive to the second DMA event signal, executing a second set of DMAs to: read and store at least one second data sample from the peripheral device without interrupting the processing component and without software intervention; and read the synchronization signal; each of the first and second sets of DMAs including its own respective set of first, next-to-last and last DMAs, the last DMA being chained to the next-to-last DMA, so completion of the next-to-last DMA automatically triggers the last DMA to perform a write operation for indicating completion of reading from the peripheral device by that set of DMAs; and responsive to a state change of the synchronization signal, interrupting the processing component to signal that the stored data samples are ready for processing by the processing component.
