A data processing device is described with a memory and a first and a second data processing component. The first data processing component comprises a control memory comprising, for each memory region of a plurality of memory regions of the memory, an indication whether a data access to the memory region may be carried out by the first data processing component and a data access circuit configured to carry out a data access to a memory region of the plurality of memory regions if a data access to the memory region may be carried out by the first data processing component; and a setting circuit configured to set the indication for a memory region to indicate that a data access to the memory region may not be carried out by the first data processing component in response to the completion of a data access of the first data processing component to the memory region.

Data processing device and data processing arrangement for accelerating buffer synchronization

For reconstructing a data clock from asynchronously transmitted data packets, a control loop is provided which includes a controlled oscillator. An input signal of the control loop is generated on the basis of the received data packets. At least one high-pass type filter is provided in a signal path of the control loop. The data clock for the synchronous output of data is generated on the basis of an output signal of the controlled oscillator.

Method and device for reconstructing a data clock from asynchronously transmitted data packets

A method and a system for providing information for recovering a clock frequency via a data network comprise generating a value representative of a frequency difference between a clock frequency and a reference frequency by using a digital phase-locked loop at an ingress interface of a data network, transmitting the generated value over the data network, and recovering the clock frequency at an egress interface of the data network by using the reference frequency and the transmitted value. Other systems and methods are also disclosed.

Method and system for providing information for recovering a clock frequency

At an ingress interface of a data network first information data are generated, at an egress interface of the data network second information data are generated, correction data are generated on the basis of the second information data, and at the egress interface a clock frequency is recovered on the basis of the first information data and the correction data.
