Abstract
A paging apparatus for improved mapping of virtual addresses to real addresses, addressing physical devices coupled to various communication buses, and controlling flow of data. By means of an eight-bit addressing apparatus activated for certain instructions which normally can address only 256 locations, an additional 512 locations can typically be addressed by generating control signals to modify a virtual address into a real address capable of addressing the additional locations. Additionally, the apparatus can control flow of data by enabling or disabling data control apparatus.
