Abstract
A computer system utilizing an N bit word in which a directly addressable space is limited to 2.sup.N-1 words or 2.sup.N characters by the system architecture. Extension of this directly addressable space to 2.sup.N words is accomplished by a combination of a memory management circuit and a character selection signal instructions which allows both characters and words to be mixed in a first 2.sup.N-1 words of directly addressable space and words only to be addressed in a second 2.sup.N-1 words of directly addressable space.
