Abstract:
An input-output bus manager system for connecting a variety of device controllers to a processor system, the device controllers placed on an input-output bus, the input-output bus manager comprising:pins on the device controller wherein when the device controller is placed on the input-output bus, the pins drive corresponding pins on the input-output bus, sensing circuitry enabling the input-output controller to read the corresponding pins on the input-output bus and therefrom determines the number, location, speed, and protocol of the device controllers, in response to the determinations of number, location along the bus, speed and operating protocol of the device controllers placed on the input-output bus, means for automatically programming the length of the bus to just reach the farthest device controller, and means for automatically setting the operating speed and protocol of the bus signals to accommodate the device controllers.
