A system for interleaving high speed data and slower data that is serialized and delivered to a microprocessor. The typical source of the high speed data is a camera and the source of the slower data is a keyboard. The high speed data and the slower data, illustratively, are interfaced with a micro-processor in a parallel fashion. The present invention mirrors the parallel interface to the microprocessor, and mirrors the parallel interface to the sources of the high speed (camera) and slower (keypad) data. The present system formats parallel data from the sources and passes that data in serial form, typically with a clock, on a flexible cable that joins two sections of many cell phones or other hand held devices.
