Direct memory access

A memory containing a linked list of records representative of a plurality of data transfers via a direct memory access control circuit, each record being representative of parameters of an associated data transfer of the plurality of data transfers, the parameters of each record comprising a transfer start condition of the associated data transfer and a transfer end event of the associated data transfer.

A method of operating a system comprising a first component and a second component, the method comprising performing data transfer from the first component to the second component by direct memory access, wherein data transfer is performed on a channel of a direct memory access circuit, the data transfer on the channel being parameterized by a corresponding record of a linked list of records stored in a memory, the linked list of records representative of a plurality of data transfers via a direct memory access control circuit, each record being representative of parameters of an associated data transfer of the plurality of data transfers, the parameters of each record comprising a transfer start condition of the associated data transfer and a transfer end event of the associated data transfer.
