  • System for initialization of channel controllers utilizing address pointers calculated from multiplying sizes of data fields with device numbers
    Patent number: 4882672
    Abstract: A system for initializing a set of channel controllers in an information processing system reduces the time of initialization, the number of steps used in a microprogram, and necessary hardware. Address pointers of a plurality of control data areas relating to one of the channel controllers are utilized. Initialization data is sequentially read from a main memory of the information processing system. Address pointers of a channel controller are calculated by a predetermined procedure from the initialization data and a device number of the channel controller. The calculated address pointer is written into a local memory of the channel controller. Initialization is terminated upon reading an end of initilization data.
