Title:
ADDRESS EXPANDING SYSTEM
Document Type and Number:
WIPO Patent Application WO/1986/006521
Kind Code:
A1
Abstract:
In an addressing system which forms a physical address by adding a segment start address and an offset together, the contents of a segment register have heretofore been added up together by shifting them by a predetermined amount. Therefore, the address space and the segment start address were fixed. However, there is proposed an address expanding system which is provided with a register (9) that stores the shifting amount, and wherein the shifting amount is set to the register to shift the contents. There is also proposed an address expanding system in which the shifting amount is written onto predetermined bits of the segment register (2). This makes it possible to expand the address space and to arbitrarily set the segment start address.
