Abstract
A microprocessor has a common data bus coupled to a storage data register, two separate storage address registers and a storage control unit. The data register transfers data to and from a storage unit addressed by that address register selected by a gating means. The address registers can be independently incremented and decremented, and perform either a read or a write operation. All these functions are specified by signals produced from a control word held in the storage control unit.
