Abstract: A programme-controlled unit comprises a crossbar with a multiplicity of ports, a multiplicity of devices which are connected to the ports of the crossbar and can exchange data via the crossbar, and debug resources for detecting the events and states occurring in the programme-controlled unit. The programme-controlled unit described can be characterized by the fact that the ports of the crossbar comprise a diagnostic port, that the addresses, data and/or control signals which are transmitted between two other ports of the crossbar are additionally also supplied to the diagnostic port, and that the debug resources are connected to the diagnostic port of the crossbar.

Abstract: A configuration and method for operating the configuration includes first and second devices connected to one another through a cross bar and accessing one another through the cross bar for reading and/or writing data. When a read access to the second device occurs, the first device reads the data emitted from the second device when it receives a ready signal produced by the second device and supplied to the first device through the cross bar, and, when a write access occurs from the first device to the second device, the first device emits the data to be written to the second device when it receives a ready signal produced by the second device and supplied to the first device through the cross bar and the second device reads the data emitted from the first device when it receives a data valid signal produced by the first device and supplied to the second device through the cross bar.

Abstract: The disclosed A/D conversion system is designed to signal the beginning or the impending beginning of an A/D conversion and/or to request the implementation of an A/D conversion from another A/D converter. As a result, it is possible to have a plurality of A/D converters work absolutely time-synchronously with minimal outlay.
