Abstract: A circuit for memory access includes a memory access control circuit. The memory access controller is coupled to a memory and configured to perform data transfers to retrieve data from the memory. The memory access control circuit includes a timing control circuit and a transfer control circuit. The timing control circuit is configured to determine first timing information based on a timing requirement for transmitting a first data stream to a first network; and determine a first fetch time for retrieving the first data stream from the memory based on the first timing information. The transfer control circuit is configured to retrieve the first data stream from the memory based on the first fetch time.

Abstract: A method and a device for converting virtually concatenated data streams into contiguously concatenated data streams, wherein the data is transmitted in containers and N containers are combined to form a multiframe, the virtually concatenated data streams consist of X partial data streams/channels, wherein containers which are allocated in each case to the same point in the multiframe are identified by evaluating a multi frame indicator of the container, the time shift of these identified containers of the partial data streams with respect to each other is measured, and in the event of a shift being present only leading containers are delayed so as to ensure that all containers are aligned with respect to time. Each channel (KA1, KA2, . . .
