Abstract
A data processing system having an address conversion system for translating a virtual address into a real address, including a main memory for storing instructions and data and a second memory for storing an address conversion table including a plurality of entries, each of which consists of a plurality of control bits and a portion of a real address. A central processing unit executes the instruction stored in the main memory according to a microprogram. An addressing means addresses the second memory by a continuous portion, which includes the effective upper most bit of the virtual address for the address conversion and for updating of the conversion table. The main memory need not store the conversion table.
