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.
