Abstract

The Control store CS (Fig. 1) operates in a multiprogrammed mode and can perform operations defined by micro-instruction words of one program, which are contained either in its static (non-alterable) section CSS or in one of its two transient (alterable) sections CST-LO or CST-HI, while simultaneously retrieving a page block of 64 microinstruction words associated with another program (from a backing store) and loading that page into the other transient section.
