Abstract
Disclosed is a control unit including a flexible decoder unit providing control patterns for controlling functional units in data processing equipment. The control unit includes hardwired decoder logic which decodes a multi-bit key to provide primary decoded outputs as control patterns. The decoder unit also decodes one or more alternate decoded outputs for future use. The decoder includes a plurality of flexibility inputs which, when connected to an alternate decoded output, provide new control patterns and thus provides flexibility to the hardwired decoder. Because of the flexibility, the control patterns formed by the hardwired decoder can be readily changed. The flexible hardwired decoder is of great value, therefore, when design changes are desired in a computer.
