ABSTRACT:
A multiprogram control information processing system with process roll-in from a main memory to hardware of a central processing unit is disclosed. The system includes a plurality of sets of visible registers corresponding to a plurality of processes stored in a main memory. The plurality of sets of visible registers are connected with a selector connected to an arithmetic unit. The selector selects one of the sets of visible registers according to an entry number corresponding to it. A memory stores the entry numbers of the sets of visible registers and identification codes of the processes in one-to-one correspondence. When an identification code is input, the memory outputs the entry number corresponding to the identification code to the selector thereby to immediately initiate execution of the process having the identification code.
