Abstract
A control circuit manages transferring of data within a system, such as an interleaved memory. The system includes a plurality of data sources for providing an output data stream synchronous with an external timing signal, an output register for storing data available at an output of the system, and a selection multiplexer for transferring the data from the plurality of data sources to the output register. The control circuit includes a plurality of circuit blocks, with each circuit block being dedicated to one of the plurality of data sources. Each circuit block includes a detection circuit for detecting availability of the data at an output of a selected data source, and a conditioned update path connected to the detection circuit provides an update flag. A logic gate having a first input receives the update flag and a second input receives an output signal from the detection circuit for providing a selection signal for the selection multiplexer.
