ABSTRACT:
The present invention relates to a memory addressing mechanism which has been formulated to accommodate three address structures: real, based and virtual. To accomplish this result the address generation function in the memory addressing mechanism has been separated into two distinct parts, address computation and address translation. By merely changing the hardware components in the address translation part of the memory addressing mechanism and leaving the hardware in the address computation part constant, an optional memory addressing mechanism which supports either a real address structure, a based address structure or a virtual address structure can be implemented.
Further, the present invention with the virtual address translation apparatus in cooperation with the fixed address computation apparatus provides a virtual addressing mechanism which will compute and retrieve a memory word utilizing a four-segment memory address with only two memory references.
