Multidrop buses have the advantage of simplicity and extensibility, but electronically are limited to around 200-400 MHz (because of reflections on the wire from the PCB onto the Die ) and 10-20 cm distance ( SCSI -1 has 6 meters). Multidrop standards such as PCI are therefore being replaced by Point-to-point systems such as PCI Express . Multidrop buses are also used by Vending Machine controllers to communicate with the vending machine's components, such as a Currency Detector (coin or note reader). Not surprisingly, these MDB buses communicate with the MDB Protocol , a 9-bit serial protocol. EXTERNAL LINK IBM Journal of Research and Development |
